Got my hotel room booked for New Orleans. It wasn't really all that bad -- about $140 a night for the Holiday Inn Express, which is pretty reasonable for a decent-ish hotel within walking distance to the stadium on a game day long weekend. I'm pretty sure I paid twice that amount for a similar room the last time I went to see the Bills when they played the Vikings. (It was worth it just for "the hurdle.")
Tickets are definitely on the pricey side, but it's Thanksgiving and I didn't expect that they would be laying there in the bargain bin. I haven't purchased anything yet, but right now they seem to start around $250 or so for upper deck seating. I'll hold off a little to see if they come down at all, but if they stay there that's fine. We don't care where we sit so it's no big rush.
Airline tickets are actually kind of ridiculous, but again, it's Thanksgiving. I'll definitely hold off on booking any flights until later in the summer.
This should be a lot of fun. My son is arguing for watching the Detroit and Dallas games in a sports bars with fellow fans before walking over to the stadium, which sounds good to me. But oh man there are going to be some incredibly intoxicated people -- nearly all of them wearing blue and red -- heading to the stadium. Gotta make a note to stick to beer and pace myself.
Edit: Now my wife and daughter (<21) have decided they want to come along, too, and the same room at the same hotel is about half again as much as it was 24 hours ago. Oh well -- at least I got one crazy cheap room, and honestly $200/night is kind of what I really expected to pay in the first place. I just got lucky and booked the first room before they had a chance to adjust their rates to "game day" rates.
