The pool is fantastic. Zero entry works well for kids I think. I can't speak from experience because we don't have any kids. We like the Hawaiin music piped under the water and the way it seems like the pool spills onto the beach and into the Seven Seas Lagoon. The Poly is the most magical, the most convenient, has the best CMs, huge rooms, lush surroundings, relaxing atmosphere, good food and drinks (we love the Lapu Lapu). Need I say more? You'll have a blast.
I've decided that I need to go with you because you may need a tour guide. Where do you live - I'll be there by the time you leave. Or, I could meet you there. That's no problem. I can drive there in 9 short hours.
