Is your resort Adults only? Most 11 year old boys would say they don't care about something like this, I have a little brother who was 11 at the time of our wedding (big age difference, he was a surprise :) ) Anyways he acted like he didn't care about it, but he had a blast once he was there!! Is it just you and your FI that are going to be there, or is other family coming?? We had kids at our wedding, but there was a lot of family there too.......I guess it just comes down to a personal decision.....a hard one at that!! In my opinon, you are becoming a family too, and it should include your son somehow. Maybe you could do a civil ceremony at the courthouse, and then have a symbolic ceremony in jamaica along with your honeymoon. That way your son could feel like he was a part of the ceremony somehow. Good Luck!!!
