I've seen In The Heights twice. First in the mezzanine and second in the orchestra. My personal opinion, I enjoyed the orchestra more.
Hruddudu--I was in Row F and my seat was great. Yours should be too!
Actinggbugg474---Your seats should be fine. Don't worry about being too close.
Fiyero13--I would go with orchestra.
Everyone enjoy the show! It's wonderful!
