We loved our stay at One Grand Whim! It was an easy short walk to the beach for my three-year-old and my parents in their seventies. The kitchen is packed with everything you might need for any kind of meal. We came in the off-season (the week before pools opened) but there was still plenty to do - basketball, tennis, volleyball, shuffleboard, bike-riding, indoor swimming, and gym. We have already decided we'll be back!
I would suggest mentioning the beach supplies at the house. There are more beach chairs and bikes than any one family would need. There are several beach umbrellas, three/four boogie boards, a couple skim boards, and sand toys. This is an attractive peice of information and had we known, we would have saved a few hundred dollars in rental gear.
