I'm going to be proposing on the beach at GF (unless something more spontaneous happens) in a few weeks. I made a thread in the welcome section asking for advice, and some of the more popular ideas were: on the polynesian's beach during wishes, on a carriage ride at either POR or WL, also a Wishes cruise, or have dinner at Narcoossee's and do it on their deck during Wishes if you can time it right.
