Another good spot is the upper level of the Main Street Railroad Station. There are some chairs, and for pictures you will be centered straight in front of the castle. Exiting should be good too. A drawback, however, is that you can't see Tinkerbell from there. Actually, you can't see Tinkerbell from Main Street either, unless you are at the hub close to the Castle. If you choose to view from there, be sure to arrive well over an hour early as everyone exiting from the train will have the same idea and want to view it from there.
