Unfortunately Escape weddings are limited to one of three locations if they want to set up a reception meal up through their Disney Wedding Coordinator: Narcoossee's, Jiko and California Grill. You can arrange your own after-wedding meal through the resort restaurants or the ones at Downtown Disney, though. Citrico's has a great private room if your party is 12 or less, and several of the other restaurants have private sections.
I'm having mine in the St. James room at the Boardwalk and I'm having an escape, it's very similar to the White Hall. I'm doing this because I didn't want to cart my guests all over the World. I would def. ask your coordinator. If you're willing to fork over the cash they will do almost anything you want for you. I'm having a lot of things for my escape that when you book are told you can't have, but like I said if you're willing to pay the extra's they will do it for you. Hope this helps!! PM me if you have any questions!!
