My group has stayed at the Residence Inn(Resort Area) on Harbor in April. Loved it. We had a 2BR suite(4 adults & 2 kids). It was very clean and having the full kitchen really helped us save a little $$ on meals. They also offer a free breakfast every morning down in the main Lobby area...coffee, tea, juices, hot and cold cereal, scrambled eggs, fruit, toast, bagles, etc.
It would be a bit far to walk, especially in the evening when everyone is tired from playing in the parks all day, but they do have a shuttle that runs every 30 mins. or so, there is a fee for it but I don't remember exactly how much off hand...we just used our own car.
