My first trip to Disneyland (last year). Everything was just perfect. I really felt like I was transported into another world. To top it off, my sister's boyfriend planned to propose to my sister (who had no idea) after the BELIEVE fireworks show. This was the best vacation I've had in years and I didn't want to leave. I'm hoping to be able to return this year for the 50th.
PS My sister did say yes.
