Hey Adrienne, congrats!! thanks for the compliments
I didn't use Rebeca at all, I did meet her and she was very nice but we were looking for a coordinator who would handle EVERYTHING where I wouldn't have to worry about anything. Also, Dazzling Details is more of a detail oriented coordinator who goes all out on their weddings which is what we wanted. The other girls who did use Rebeca though said she was great. It really depends on what you want and your budget.
Did you get the group rate through Dreams? I thought they would be the best so I did the same and they were not. I got a few more quotes from TA's and used the best rates. It is crazy to me and makes no sense that the resort directly would not have the best rates but they don't. Also, outside TA's have better negotiating power so I would definitely do that. When our room rates lowered online, our TA got ours lowered to beat the online rates, and this happened a couple times before our wedding.
Good luck! Any questions, feel free to ask. You will love Dreams PV.
