That's easy. I've wanted to go to Australia since I was about 8 years old. Don't ask me why, because I really don't know. I guess maybe we were learning about it in school and it just fascinated me. So ever since then, it's the one place I've always wanted to go. ALWAYS. I would LOVE to go there. If I ever win the Lottery, THAT'S where I'm going.
Now, on a more REALISTIC level, the other 2 dream vacations for me are Disney WITH the kids, and Vegas WITHOUT them. I LOVE both places. I would go to Vegas every year if I had the money. Same with Disney. Unfortunately, we DON'T have that kind of money, so I'll have to settle for every few years. :(
