CONGRATS!! I got married there 10.20.13, and it was absolutely perfect.
There are a couple choices of where to get married, the lawn, the beach, and the terrace. We chose the lawn, because I really wanted to be surrounded by greenery. There are no existing structures on the beach or lawn; we did a bamboo structure with orange fabric. There is a little gazebo on the terrace, which is gorgeous and has a lovely ocean view. We didn't use that, though, because that's where we had our reception so we wanted to use more than one location. We did our rehearsal dinner on the beach with tiki torches. I wore flip flops! So can't say what it might be like walking on sand in heels. They can do a grass mat in the aisle which might help?
We did a reception because we wanted to dance and have a private dinner for the group, but I'd say if that's not a priority for you guys, would be fine to just go to a restaurant to eat. It's your day!
Let me know if you have other questions, I'm happy to share my experience at the fabulous BOR! We used the resort photographer, and were very happy with our photos though we definitely don't have any of the cool, artsy kinds of photos that I do see. Here are some, in case you're interested.....
