If you have Am Ex gold cards or better, you could wait in the Am Ex Centurion Club in Terminal 1. In general, Terminal 2 newer and more comfortable than Terminal 1. Not the most comfortable airport in which to spend several hours, but you will survive.

As noted, getting carts is no problem, but the walk between the two terminals is a long one. At least it's indoors. There are golf carts that take passengers between the two, though no carts permitted. I don't think you're supposed to take the carts on the moving sidewalks, but those don't go the entire distance and may be out of order, anyway.
