Arrive Krabi International Airport at 20:45. Collect luggage and take a pre-booked airport transfer to your hotel (Ao Nang or Krabi Town) — with a baby choose a private transfer for safety and car seat if available.
You wrote '2 nights in Krabi and three Koh Lanta' but arriving Oct 10 and departing Oct 16 requires 6 nights; 2 + 3 = 5 nights. Tell me which nights you actually booked (specific dates in Krabi and Koh Lanta). Do you want (A) 2 consecutive nights in Krabi at the start and 3 nights in Koh Lanta, then return to Krabi early on departure day to catch your 11:45am flight (requires very early ferry/transfer), or (B) add/keep a final night in Krabi (safer, recommended for traveling with a baby) so you have an even, relaxed schedule? Reply with your confirmed hotel nights or which option you prefer and I’ll generate the full day-by-day plan with meal picks and checked opening times.
