I completely agree with your choice to take just the M7 and 35mm Summicron. I'd make just one other suggestion. Instead of taking several rolls of film with you, just load one in the camera and have it hand checked. When you get to NY, buy film there (42nd street is loaded with camera stores). Then, before you return, find a lab that can give you a quick turn-around (there are some that will give 2 hour service) and get the slides processed before you return.

The reason for this suggestion is that the x-ray devices are becoming more potent and unpredictable. Additionally, some security agents get baffled and leave your items in the x-ray until they can figure out what it is. In some cases this can be up to a full minute of exposure. Even for slow films, you can get burned.

Have fun!
