Last October we took our daughters (30 & 26) to Disney World for a week. We did the full resort stay complete with the meal plan and had a WONDERFUL time. We go to Disneyland all the time since we are only 90 miles away. But had not been to Disney World and have wanted to go since they opened 40 years ago. So what better way to celebrate Tiffany's 30th birthday but to go to Disney World. It was all they advertise and more. Everyone was so nice.
So I hope that you and your DGD have a fantastic time!
