I wouldn't mind hanging out with them, but they picked the freakin first weekend of Mardi Gras to come down. Makes it unlikely I'll be able to or want to head up to the north side of Houston, which takes about 1 1/2 hours on a normal day and all bets are off that weekend. The second weekend is bigger, but traffic still sucks the first.
Bleh. Maybe 10% of the weekends of the year at most I wouldn't be able to join them, and they pick this weekend.
It may end up being awkward in other ways, it may end up fun. It's unlikely to end up in a drunken orgy. Oh well.
