Land early morning; use pre-booked hotel transfer to Riverside hotel to drop luggage and rest—fast-track immigration if you have eVisa/ETA printed. Expect 45–75 mins from plane to hotel depending on queues.
Private long-tail to quieter islands (Koh Hong / Koh Rok options if sea calm) for swimming/snorkel — tailor pace to your comfort. Typical start 8:00–9:00am. Check sailing and weather each morning.
Early lunch and check-out; schedule afternoon flight back to Bangkok (recommended early evening) if you prefer to overnight in Bangkok before international flight.
If you fly today, arrive Bangkok and overnight near airport; if departing next morning, enjoy final restful night at the resort. Keep door-to-door under 4 hours where possible.
Aim to be at Suvarnabhumi 2.5–3 hours before international flight to Bengaluru. If flying from Krabi same day, door-to-door could be tight; recommended to overnight near BKK.
