We're going to Las Vegas in September. I'm excited. I've never been before. We're just going for a long weekend (3 days, 2 nights) but it'll be fun. We're staying at the Plaza (which is downtown, I think) and we're going to see Mystere (Cirque Du Soleil) at Treasure Island.
I haven't been on an airplane since I was about 7 years old. I'm excited about that part too!
Here is a link that might be useful: Mystère!
