I'll be returning to Oktoberfest this year, after falling in love with it last year. The only thing to be aware of on the 16th is that's also the Rosaweisn, the gay day at the Braurosl tent. That one will be packed and have a line all day, so check out one of the other tents. Last year was rainy but there were plenty of spots in all the other tents. A nice sunny day would change that by a lot though!
