My family and I will be in Koh Samui for five nights, then on to Koh Tao for three, then back to Koh Samui for only ONE night before we fly to our next destination in Thailand. For that last single night, I'm at a loss on where to stay (the rest of the hotels are booked). I'm looking for a hotel that will be convenient to airport, as I don't want to drive far from the ferry and back to the airport the last night. My only requirement is that the hotel has a decent pool, as I have children that will want to swim. I'm thinking maybe a three star, under $100 for a family of four. Any suggestions?
