Clear immigration, buy a Singapore Tourist Pass (or use ez-link) and take the MRT/taxi to a recommended 3★ hotel (Hotel Boss or ibis on Bencoolen) in central Singapore for easy access to Little India and Marina Bay.
The outdoor gardens are free; the cooled conservatories (Flower Dome & Cloud Forest) are highlights and worth the entry for first-time visitors. (Conservatories typically open 9:00am–9:00pm; check before visiting.)
Annalakshmi (near Chinatown/Esplanade) and Gokul offer extensive vegetarian Indian menus with good portion sizes; quiet, budget-friendly dinner options.
Travel via Sentosa Express or cable car; choose relaxed beach time (Palawan/Siloso) or visit S.E.A. Aquarium (opens typically 10:00am–6:00pm) for one of the world's largest aquariums.
Choose the National Museum for Singapore history or ArtScience Museum for rotating exhibitions; both close late afternoon/evening (check current opening hours).
Take MRT to Woodlands, cross at Woodlands Checkpoint by shuttle/bus or taxi; cross-border immigration can take 30–90 minutes depending on time of day. Bus/coach to JB Sentral is cheap and frequent.
Check in at a centrally located 3★ hotel (e.g., Hotel ZON/JB smaller 3★ options) and enjoy a vegetarian lunch at a local Indian or Malay vegetarian-friendly restaurant.
Walk the compact old town, visit the grand Sultan Abu Bakar Mosque for architecture and views of the Straits (mosque visiting hours vary; dress modestly).
Book an express coach (comfortable coaches depart frequently) or intercity train to Kuala Lumpur; daytime travel offers scenery and arrival into KL Sentral in the afternoon.
Walk the lively shopping district; Pavilion and surrounding streets have vegetarian restaurants and cafes. Good for evening shopping and people-watching.
Visit the iconic Batu Caves Hindu shrine (open early — typically 6:00am–9:00pm). Climb the 272 steps to the main cave; early morning avoids heat and crowds.
Walk the KLCC Park and visit Suria KLCC mall; visit the Petronas Skybridge/observation if tickets available (check opening times — typically 9:00am–9:00pm; pre-book recommended).
Choose Genting for cooler mountain air and Awana Skyway cable car (opens early); Putrajaya for architecture and lake views. Both are ~1–1.5 hours from KL by coach/taxi.
