POR is a great location for pictures!
For ours, we decided we wanted highly themed resorts, so we did the Polynesian and Wilderness Lodge. It sort of depends on the look you're going for. The Grand Floridian is good for classic and classy. The Beach Club and BoardWalk are more laid-back classy... Another time we did a shoot at Bay Lake Tower and the Contemporary because we love the sleek, modern look of some of the spaces (not all of the spaces though!).
