I don't know about the Poly or GF, but you can have one on the beach of the WP, pricing I think is the same as the WP since it is your back-up location if it rains.
It's something me and my partner discussed but we weren't sure if they would allow it on an Escape package, so we talked ourselves out of it and into the pavillion.
I havn't asked my co-ordinator though so it may be possible!!
You can have a wedding at the beach at the Grand Floridian for a Wishes wedding...not Escape. You can not use the beach at the Poly for a wedding. However, they do have Sunset Pointe at the Poly that still gives you that tropical feel.
