I'm planning to return to Munich in 2014, having last visited in July 2008. I'm trying to decide whether to go in mid-July or September (before Oktoberfest). We probably won't return to the museums or other major sights, but instead focus on biergartens, strolls, seeing a Bayern Munich match, and generally taking in the atmosphere.
Is September any less crowded or cheaper than July? Would I be paying inflated Oktoberfest prices (for hotels, etc) a week before it begins, or are the prices only higher during the event?
