Hi Dawn!
We stayed at Barcelo Tropical over Christmas of 2006 with our kids who were 6 & 3 at the time! It is a fantastic resort for familys! The pools are gorgeous & my kids LOVED the kids waterpark! The kids had to be 4 to be left at the kids club so just my daughter went.....but you can use the facilities with the younger kids as long as you stay with them. They have a little climber there.....The beach is gorgeous...the buffets have a little part especially for the kids! We parked ourselves near a shallow end of the pool in the afternoons (when not on the beach) and the kids played & enjoyed themselves! We thought the food was great & they were very accomodating at the A la Cartes for the kids! Have fun!
