We just got back the other night.
We went with another couple and their two kids. We had a great time!
Anyone looking for a great family vacation should def. look into Naples.
We stayed at the Ritz Carlton Beach Resort. Everything was amazing. We got the summer family package and it included a coastal view room, breakfast for 2 adults and 2 kids, $50 resort credit daily, and a $50 gift card to the Waterside shops (which were amazing!! great shopping!!) They also had a family pool which we hung out at most of the day. Weather was great during the day, with a rainstorm at night that lasted for about 20 min.
The hotel also had a Natures Wonders kids program, but my daughter was too young for it, however we had access to the aquarium daily from 4:30-5:30. Also, there was a game room with plasma tv's, wii games, playstation, computers.

We will def. be going back to Naples very soon!!
