This falls outside of FT, maybe there is a BusriderTalk forum somewhere, but rent 1 or 2 busses to go down there, 24 drive back and forth and you'll fit your 50 or so people attending (a motorcoach is usually 42 seats if I recall correctly) if you all really plan on attending.

Ad for destination weddings, i'm not against it, but plan it ahead of time, and if possible, not during the most expensive day/week of the destination! They can be lots of fun, a nice vacation or long weekend to be with friends and family. I disgress, but they arent necessarily cheaper than an In town wedding, when you add all the gifts, clothes and prep necessary (especially for the ladies)
