Was planning to go to the on by the bridge (no idea what DUMBO is).
Do you think it is too much? Should i save moma for friday?
I agree with everyone that 3 museums is too many in 1 day. No way you would get to see or appreciate everything in each one. I think 2 at the most, and that's plenty.
The subway is the best form of transportation unless you're going to or coming from LGA/JFK. Cab would be the best bet there (no subways at the airports).
