We made plans to take our girls to Disney.  We told them we were going to the beach.  It was a big surprise for them and I think I was as excited to see their faces and they were once we got there.
When our girls were 5 and 7 we made plans to take them to Disney, but we didn't tell them where we were going.

Oh that was a wonderful surprise?  What was their reactions?

Well, at first they were like "But we wanted to go to the beach!" because that's where we told them we were going.  But that faded quickly as they realized where we were staying and what we were doing.  I loved seeing their faces!
