My brother and I are going for the first time. We'll be in Munich for about 6 days and plan to spend about 3.5 days at die Wiesn. We didn't make any table reservations, but from what I've read, we should be able to find some seats since there's only 2 of us. I'm sure that'll depend on the days of the week. We are there through Italian Weekend and our plan is for Thursday evening, Friday, Sunday, and Tuesday. The day I'm most concerned about is Friday.
