Hollym,
I am getting married at the Iberostar Dominicana next August. I assume that Yoselina is your WC. I actually met with her in October to see the different locations for the ceremony and a reception and she was great. She is very efficient and organized. As long as you come with a list of everything you to see happen, she will figure out a way to do it. We have a lot of complicated circumstances and she came up with a solution for everything. Also, you don't need a deposit at the Iberostars. I was worried about that as well, but then she showed me the master calendar with all of the reserved dates. I hope this helps!
