I saw a wedding the last time I was there in the pier gazebo. It was beautiful, but a small wedding... maybe 5-7 people.
I have pictures from my last stay but it was 2001, so things may have changed since then.
THe other part I love about this one is that you are not literally NEXT TO the airport. At the Sandals Mo Bay, the waiters at the restaurants wave to the planes when they go by! Also... you have rights at all properties on the island, so when you are looking for a party, head to Mo Bay for an evening. We did. Otherwise, I loved the laid back feel of Royal!
