Unless you plan on actually going into the Grand Canyon and doing some hiking or rafting I would skip it. It's out of the way of everything and it's really not that great once you get there, at least if you just plan on going and looking down at it, you're just gonna look down and think, "That's a big ass canyon." San Fran and Yellow Stone are both good ideas. NYC is a great city, highly recommended. Southern California is awesome, but you have to think logistics. If you aren't going to have a car, it's going to be a tough place to be if you want to go out. The beaches are worth checking out regardless. Colorado has great scenery and tons to do. If you hit up Southern California, Vegas is a 3-4 hour drive.
