Most have a complimentary ceremony especially for ROV/Symbolic (which my understanding they mean the same). There is a vendor on here that owns a small resort which may be an option. I can send you the location if you PM me.
I would recommend focusing on your wish list, guest needs and then compare the various resorts. I'm a bit geeky so I created a resort analysis chart. It's in my blog...you can update it to meet your needs.
