I went down there last August with my girlfriend for the a two game series when the Brewers were playing. We only went to one game, but it was definitely a good time. We sat in the right field bleachers (section 508), and I think the tickets ended up being $25-30 each, including fees for ordering online. I have no complaints...the bleachers were field level and had a decent view of everything except plays up against the right field wall. I'd definitely recommend any of the bleachers in Busch though if you're looking to stay on the cheaper side. We got to the game when the gates opened and checked out all the levels of the stadium, and also sat down along the 3rd base line in left field while the Brewers warmed up throwing before they took batting practice. Got some awesome pictures that way. I don't know who the Cards are playing the weekend you're going, but if you apply yourself you should be able to get some autographs or a ball if you wanted down there. Just go early. We also sat in the left field bleachers while BP was going on and came really close to getting a few BP balls off ones over the fence. You should be fine wearing your Brewers gear, especially if it's not against the Brewers. The fans around us were all pretty cool, and if you have anyone in your section wearing Cubs logos, they'll definitely garner the most attention so the Cards fans will forget about you anyways. If you have time I'd recommend going to the stadium early in the afternoon and taking a stadium tour. It was $10 each, lasted an hour an a half. Got to see all the standards like the radio booths, etc. Since we took the early tour though, we got to go down in the visiting dugout and then walk around the warning track for a few minutes behind home plate and got some really cool pictures that way if you're into that at all. If you think of any specifics to ask, let me know. ewizabeff, if you guys haven't looked at hotels or anything yet, I'd recommend the Millenium Hotel. Rates were reasonable if you get the room through hotels.com or something, and it was halfway between the arch and the stadium. Location couldn't have been better, also right off the freeway and easy to find. A ton of Brewers fans hanging out in the lobby areas too.
