Hi again Ian,
I took your advice and tried to book KB resort, and they are booked for my travel dates. At least I think they are- when I called I'm not sure if the woman I spoke with understood me. She wanted me to take a 4- person family room for 4000 baht/ night; what I wanted was a beachfront double. (My kids are 2 and 4- they can just sleep in a bed with us). Is the beach at Klong Prao better anyway? The pics of Hat Kai Bae look like the beach is very narrow.
Anyway, so I'm on to my second, third, etc choices. Paradise Resort or KP Huts? Which is better in terms of beach quality, both for nice sand and safe, shallow water for the kids to swim? Proximity of rooms to beach, food at the resort? Which place has more "character"? I would like the option of a couple other places walking distance for a drink or meal, but someplace still quiet. I know KP Huts doesn't have a pool, but my kids love the beach so much that they wouldn't notice.
By the way, I also looked at the sailing charter companies you reccomended... we are booked for 3 nights on a catamaran. It looks amazing. Thanks for your help with that. Now I just need to wrap up the plans with 2 nights at a resort after the charter....
