I got my tickets in May and they were just starting to go up. I could’ve flown in from SF for under $400. I waited a week and paid like $440. I may not be the one deciding whether I can go or not. I have two sets of friends getting married next year and I don’t know when. Chances are one wedding will be in the middle of GenCon and the other in the middle of the Beer Bloggers Conference. I seriously doubt they will conflict with FMGC13 and Spring Gathering XI.
Once you go…you gotta go back.
Get airline tickets in February (or earlier) and that saves costs. Also, try and get into the gencon housing block on the 1st day, which also is the lowest local hotel prices.
