re: Oktoberfest Trip-any additional cities to see?

Thanks for the recommendations so far everyone. Never been to Munich or Germany in general. We get into Munich Monday afternoon and probably plan on leaving Thursday evening for either Amsterdam or Prague now. We plan on flying to Amsterdam if we do. We fly out of Paris the following Monday so we will likely return to Paris on the Sunday before. We are on this trip to party hard and meet/party with the local womenz. One of my buddies is running the Berlin marathon and a few of us are meeting in Munich after that. We have the Oktoberfest tent tickets too which I heard if you don’t its like tailgating outside of the stadium while the big game is going on.
