We are celebrating being hitched for just over 3 years. We we searched for the right venue for our reception I took a deep breath during our first meetings with all venues and asked if they hosted gay weddings before. I would also followed with "how comfortable is your staff who will be working our reception".
I'm happy to share that the country club we chose stated we were their first gay wedding. They assured us that they asked the staff for our reception to volunteer to work to be certain that they would be comfortable.
It was a huge success! Occassionally when we go back for open to the public events, some staff still remark how our wedding was the best they ever attended.
So...go boldly. Be sure to ask. Watch for the response. Decide from there. BTW...2 other same sex couples got married and held their reception there that same season.
Best of luck. Remmber this is a celebration for you both and for your family. Two final pearls of wisdom...
1) be prepared to be the recipients of so MUCH love on your day and events surrounding
2) get everything done 3 days before your wedding weekend. Embrace our position of "if it's not done too bad. We choose not to worry about it!"
Cheers and the very best to you both
