Getting the judge to get back to the hotel takes a while, at least it did for me and I requested my wedding day/time more than a year in advance! Even then, he wasn't available the day that I wanted to get married...he was only available the day before at 2pm. I didn't want my ceremony to be on Friday or that early so Marlene gave me the option of meeting with the judge on Friday, signing the paperwork then and having my symbolic wedding the next day. At first I agreed, but then changed my mind since it seems like such a hassle getting all the paperwork together just to have your wedding there. So I gave up the judge and opted to get married in the states before we arrive in D.R. That said, once she does get back to you and, God forbid, it turns out to be at a time you don't want, you can quickly get married in the states and not have to worry about having the time you want once you get down there.
I hope that eases your mind a bit.
