432 had a great view of the outfield and a so-so view of the infield. I didn't find the beer hawkers to be very accessible since they only came up thru maybe once an inning; probably has more to do with the weak upper level attendance. But I wouldn't want to climb up and down the steep steps too often during the game either.

Getting here can be a little tricky. You'll have to enter the Union Station entrance (main entrance) and take the escalators that you see up ahead. From there, just walk all the way around until you see section 432's entrance. Navigation was very easy but this is a big ballpark so it takes a little while to get around. There are stairs that are closer but the escalator is a much easier way to travel.
The Outfield Deck is a pretty neat place to watch the roof close/open but you need to be at quiet a few home games before you eventually see it happen. Astros baseball always takes place during the blistering hot Houston summers so the roof stays closed most of the time.
