Hilton head with cousins
Cruises with grandparents — loved the stuff like climbing walls, trampolines, lots of control over their food, catamaran trips with slides and snorkeling
Grand Tetons — bison in toad were very popular. Horseback riding. Rafting.
Costa Rica — we stayed at SJ como no and the kids loved the small resort feel and the water slides and swim up bar in the pool.
