Backstreet Boys fans uniteeeeeee!!
1.5 hours of amazing nostalgia and fan girl giddiness (Be prepared for essentially 1.5 hours of karaoke-ing with fellow fan girls). The boys still got it!
Souvenirs are sold inside the venue or at a store outside in the shops. Apparel is kind of tacky, but I guess that's a blessing in disguise (no temptation to spend $70 on a hoodie!).
Tip: If you're going to the after party, you don't need to buy the tickets straight from BSB. Find a guy standing outside of the Paris hotel and put your name on the Chateau guest list. It's $10 cheaper than buying it from BSB, you get 2 free drinks, and you're in the "Guest list line" (aka the shorter line) versus the General admission line. Go straight from the show to the club (next door) and stake out your spot right next to the VIP area. Some of the guys will walk along the perimeter of the VIP section and take selfies with people, so make sure you get a spot RIGHT IN FRONT. They get there around midnight and leave at around 2am.
