There are no official rehearsals for Escape weddings. It's a simple ceremony and your wedding planner and officiant will walk you through it pretty much the day of the wedding.
Where are you getting married? I honestly don't know if you can do a run-through on your own at the WP - does anyone else know??
I wanted to do a quick run-through so my daddy knew where he was walking and my MOH (our only attendant) knew where to stand and practiced holding my bouquet and fluffing my train. Since we got married at WL Sunrise Terrace we were able to do the run-through on the Terrace the night before, and then enjoyed dinner at Artist Point. For rehearsal dinner it was just us, my MOH, my daddy, and DH's parents. I'm glad we did it, since much of our wedding was kind of non-traditional (no reception, no dinner), it was nice to have this tradition. It also really put my MOH at ease, she was worried about where she needed to be and what she needed to do.
ETA: My wedding planner arranged our actual rehearsal dinner reservations, but I don't know if that's typical because I've read on the boards that usually with and Escape wedding you're on your own for reservations. HTH!
