Have used both of these before.

theatremonkey.com has good information about views from specific seats in specific theaters. For example, some theaters have flat floors with the seat directly behind one another instead of a sloping floor with offset seating, so the stalls is not the best choice there. You get that sort of information from theatremonkey. There's other info. too.
