Wa Ale really is an incredible place! I am not sure how the visit would work using points as I did not go that route for our visit. As far as taking young kids, it depends how comfortable you are taking your kids to the beach. The staff are very helpful and they
are with you for all excursions but otherwise there are not posted lifeguards on the beach that I saw. I would not stay with young kids in the treehouse accommodation as the stairs are steep and the treehouse is well off the ground. The Tented Beach accommodation has a lot of extra space so if they agree to accommodating kids, that should work. If you have the available finances, there is also the option of the private Beach House with a large private beach, personal chef, and butler. It has four bedrooms. Even if you are not at the private Beach House, the Wa Ale staff are very accommodating in regards to meals and I would guess they would fix food that your kids would love.The best way to get specific answers to your question would be to email/message Wa Ale and Holly should get right back with you.
