It's my first trip to DCA, and I don't remember DLR at all since I went there once when I was eight and once when I was five, before DCA existed. I'm so excited!
The only ride I remember at DLR is the storybook boat ride that had the little villages in it and that was my favorite. Also I remember my sister being all psyched for BTMRR, and I was scared of it, but then she was scared and I ended up going on it
EDITS: And I actually earned the trip too, because I placed 4th in an event that had more than 10 people in it! (I placed 6th in the event last year, and they take the top five, so I was really happy about that). I also placed 2nd in Java Programming, out of two people.
