We've stayed at all three and they are all good! We went to Cebu just over Easter with 6 and 3 year old and they both loved it! Staff was great! short flight and only 10 minutes from airport! Older one snorkelled and Jet Skied with dad. You can borrow life jackets (which we all did then "floated" out to the dock for fun!), sand toys, can rent the snorkels, kayaks, jet skis. the kids also loved all the fish! Staff would give you bread in the mornings to feed them. The pool has one water-slide and a smaller child's pool. They do have a playroom with the big slides in it but we were there for only 1/2 hour as kids (and mommy!) wanted to spend most of the time at the beach! They also have big mattresses for the sand that you can borrow and my little one napped on it under the umbrella!
The 2 in KK are both good also! Personally I wouldn't do the Rasa again as the long drive to get there to see the monkeys wasn't worth it.
Enjoy your trip! You can't go wrong!
