Surprise trip to Disney World

We told our 5 y/o daughter that "daddy was going on a business trip". She didn't know we were going to surprise her with a trip to the Magic Kingdom to meet the princesses. She knows the characters, but she doesn't know what "Disney World" or "Magic kingdom" are. This was also her fist time on a plane. She was a bit perplexed, not knowing exactly what was about to happen :o)
