I went to the DC show last night and it was amazing. A few things...
-The reflection section is the SAME as GA! The only difference with the VIP package is that you get in earlier (we got to go inside early but they didn't let us down to the floor until like 3 minutes before the doors open) to get a "better" spot.
-The reflection section got really crowded! We had just enough room to dance and it was so fun, but if you plan on trying to get a spot touching the stage, it gets tight.
-There was no age limit for the reflection section, we had a lot of children in ours.
-The best spot to stand if you want to interact with Katy is at the point of the triangle. If you don't get a spot here, I wouldn't really worry about getting a spot along the catwalk since she doesn't really stop on the sides. Many times I had just as good of a view (if not better) standing in the middle of the pit (which was the least crowded place).
Finally, the show was AMAZING! She played for a while.... like over 1.5 hours (almost 2) and I loved EVERY second!
