We went to Atlantic Beach in North Carolinas when my daughter was 2 and my son was about 9 months. It was wonderful. We wnet with my husbands parents, aunt and uncle and all of the uncles brothers and sisters and neices and nephews and uncles parents(40 people all together). We all rented different condos in a row. There was many children and teenagers to help with watching the children so husband and I could go out. I would suggest seeing if someone else could come too just to watch your daughter when you want to go out. There was an "amusment park" for children and putt putt near the condo. It was a really great time. The pool was right by our place so we sat at the pool with the baby monitor when the baby was napping! We were about 100 feet from the ocean!
Good Luck
