My onsite coordinator got in touch with me this past week I'm still over 4 months away from my wedding. i just confirmed with him that i wanted to book the sky terrace for my ceremony. So maybe you wont have to wait that long after all. Just ask about getting in touch with your onsite wc. They'll be able to do it for you quickly with no problems. Honestly I feel a lot better now that I have been talking with the onsite wc. He just sent me all the menus, private event locations, centerpiece, cake options, etc. I feel like I can really dive in now!
