Start with around two hours at the swimming pool at your Nagoya hotel, ideally from about 8:00–10:00am before the pool becomes busier. Keep the 1½-year-old in shallow water with constant adult supervision, and bring swim nappies, sun protection, and a dry change of clothes. After changing, take a short GrabCar ride—usually 10–15 minutes, depending on your hotel—to Nagoya Hill Shopping Mall, Jalan Teuku Umar, Lubuk Baja. The mall generally opens around 10:00am and is useful for children’s clothes, nappies, snacks, and pharmacy items; it is large and air-conditioned, so use the stroller rather than trying to carry everything.
For an early lunch, continue by Grab or taxi for roughly 10 minutes to Waroeng Lamongan “Cak Ali”, in the Nagoya area. Order family-style ayam penyet, fried rice, vegetables, and plain rice; request mild sambal separately for the children. Allow about IDR 40,000–90,000 per person, with the exact price depending on drinks and shared dishes. After lunch and a proper nap break, head to Funworld Nagoya Citywalk, at Nagoya Citywalk, Jalan Imam Bonjol, Lubuk Baja—typically another 5–10 minutes by car. This indoor arcade and ride area works well for mixed ages, but check each ride’s height and age guidance; budget around IDR 100,000–200,000 per child for play credits. One adult can stay with the toddler in the seating area while another accompanies the 4-year-old.
Finish at Nagoya Food Street, around Jalan Imam Bonjol and the Nagoya entertainment district, arriving around 5:30–6:00pm before the busiest dinner period. Walk rather than adding another vehicle journey if your exact exit from Nagoya Citywalk is convenient; otherwise, a short Grab ride is simplest. Choose freshly cooked noodles, rice, grilled chicken, satay, or simple seafood portions for the children, while adults can try Batam-style seafood and local snacks. Expect roughly IDR 50,000–150,000 per person. Bring cash in smaller notes, keep the stroller close in crowded lanes, and leave once the children tire—the food stalls become livelier and less comfortable for toddlers later in the evening.
Leave Nagoya around 7:00am for the southern-island boat transfer to Abang Island Sea Turtle Conservation area. The drive to the departure point near Galang is roughly 1½–2 hours, followed by a boat ride; allow at least 3–4 hours altogether. This outing is weather- and tide-dependent, so confirm the boat and conservation-site opening with the operator the day before. Bring hats, reef-safe sunscreen, drinking water, snacks, spare clothes, and life jackets suitable for both children; keep the 1½-year-old within arm’s reach near the jetty and boat. Expect a simple, educational visit rather than a polished attraction, with a contribution or tour fee commonly around IDR 50,000–150,000 per person, excluding transport and boat costs.
Continue along the Barelang route to Barelang Seafood Restaurant in Galang for lunch, allowing about an hour. Order grilled fish, prawns, squid, and rice for sharing; prices generally work out at about IDR 100,000–250,000 per person depending on the seafood chosen. Confirm the total price and weight of seafood before cooking, and request less chilli for the children. After lunch, stop at Maha Vihara Duta Maitreya Temple, Sei Panas, for approximately 45 minutes. The spacious grounds and colorful statues are easy to explore with a stroller, but dress modestly and keep children quiet around worshippers. The temple is usually open from morning into the afternoon, with no standard admission charge. Allow roughly 30–45 minutes from the restaurant to the temple, then about 20 minutes onward to Batam Centre.
At Kidzooona at Mega Mall Batam Centre, plan about 1½ hours of indoor play, normally from late morning until evening; verify the day’s session hours and entry price at the counter, as rates and required socks can change. Budget approximately IDR 80,000–150,000 per child, plus socks if needed. One adult should stay with the 1½-year-old, while the older child enjoys the supervised play zones. From Mega Mall, take a Grab or taxi to the pre-booked nail and hair salon in Nagoya—allow 25–40 minutes depending on traffic. Reserve a 2–3-hour appointment specifically for hair coloring and manicure, and have another adult take the children to the hotel or a nearby café; coloring times can run longer than expected, especially with a full-head treatment.
Finish at Teras Café for a relaxed light dinner and drinks, approximately IDR 60,000–150,000 per person. It is a practical post-salon stop for Indonesian and western dishes, but call ahead if arriving with a stroller or a larger family group. From the salon, the café should be a short Grab or taxi ride; keep the evening unhurried after the long southern-island excursion, and arrange the return to the hotel before the children become overtired.
Start at Nagoya Hill Shopping Mall, on Jalan Teuku Umar, Lubuk Baja, around 10:00am when most shops are open. Allow about two hours for clothing, toiletries, children’s supplies, snacks, and last-minute holiday items without having to cross the city repeatedly. Hypermart Nagoya Hill is useful for nappies and packaged snacks, while the mall’s fashion shops and Matahari Department Store cover children’s clothes and basics. Use a taxi or Grab with the mall’s main entrance as the destination; the covered parking and lifts make it manageable with a stroller. Keep purchases light until later, as you will still be travelling to Batu Ampar and Batam Centre.
Take a Grab or private car to Harapan Seafood Restaurant, at Komplek Batam Sentosa, Jalan Yos Sudarso, Batu Ampar—roughly 15–25 minutes from Nagoya Hill, depending on traffic. Order local favourites such as gonggong, grilled fish, prawns, kangkung belacan, and rice; expect approximately IDR 100,000–250,000 per person, with seafood charged by weight, so ask for the price before cooking. After lunch, continue about 25–35 minutes to Ocarina Batam, Jalan Bunga Raya, Sadai, Batam Centre. This open-air waterfront park is best treated as a relaxed toddler walk rather than a full attraction circuit: go for the shaded areas, breeze, and space to move, and keep the visit to about 1½ hours. Bring hats, water, and mosquito repellent; the midday sun can be intense, and some rides or facilities may operate irregularly on weekdays.
Return to the Nagoya hotel for the planned final swim, shower, and an early children’s meal or nap. Keep this as downtime rather than squeezing in another attraction—after shopping and two cross-town drives, the 4-year-old and 1½-year-old will appreciate familiar surroundings. For dinner, head by Grab or car to Golden Prawn 933, Jalan Golden Prawn, Bengkong Laut, around 15–25 minutes from Nagoya. Its spacious setting and broad seafood menu work well for families; budget approximately IDR 100,000–250,000 per person, and confirm the seafood prices before ordering. Once the children are asleep, arrange a licensed in-room therapist through the hotel or use a reputable Nagoya provider such as K Spa Massage, at Komplek Nagoya Garden, Jalan Imam Bonjol, Lubuk Baja; confirm availability, therapist gender, treatment duration, and childcare arrangements in advance. Allow 1½–2 hours, and avoid leaving the children unattended—one adult should remain with them throughout.
