As Angey77 stated, the ADH stands for the Atlantic Dance Hall. For those of you who are unfamiliar with this venue, it is found on the boardwalk: click here.
So far I have held two dessert parties at the Grand Floridian's marina. One of the parties was held immediately following my Summerhouse dinner event, and the other party was held on the night before my Fairy Tale Weddings vow renewal. When I finally post photos of that second dessert party, I promise Ill post a link to them here.
Thanks everyone for the abbreviation help I was a little embarrassed that I didn't know The NAPA room looks cool, as does the Atlantic Dance hall. I was considering doing a Wedding pavilion ceremony around 1:00 since it's a little cheaper, but then I wanted to have the dinner coordinate with Wishes so that we could go outside of the California Grill and watch Wishes after the dinner. Any suggestions since that is a HUGE gap in time?
