To keep a day going with children in the rain, Aonang Phu Pi Maan Resort and Spa is the first candidate to compare. An indoor pool, a free kids club, a library and kitchen rooms make long hours at the hotel easy, and Ao Nang's centre is about 1 km away in a straight line when the rain stops.
Centara Life Phu Pano Resort Krabi suits groups with many children thanks to bunk-bed rooms, a playground and an indoor pool, while Red Ginger Chic Resort and Aree Tara Resort are small hotels for walking to and from Ao Nang. With modest facilities at the latter two, fill rainy-day plans with massage and outside restaurants.
Railay Princess Resort & Spa has a kids club and an indoor pool so you can stay in whatever the weather, but the boat transfer is a given. Rough seas can make the boat uncomfortable, so leave slack on arrival and departure days.
Hotels outside Ao Nang make the facilities the centre of the plan. Amari Vogue Krabi fills a day with its private beach and indoor pool on Tubkaak Beach, and Pimalai Resort & Spa with its kids club and tennis court on Koh Lanta. Put the transfer time into the schedule first for both.
Flight and hotel rates vary by date. With rain in mind, check the free-cancellation deadline, and confirm breakfast inclusion and transfer options on the listing.
