Anne, does a place like Embassy Suites work for you? The Embassy Suites in Maui is just past the town of Lahaina and just at the far edge of Kanapali Beach. Rooms are large two room Suites with two TV's and small kitchenettes and dinette tables.. Breakfast is included, and so is an evening cocktail party. There is a very kid friendly pool with slides , great beach and they even have minature golf.
Stayed there on our last trip and folks with kids were very pleased.
