Married in the beach in Hatteras with topical storm waves pumping then honeymooned it in El Salvador. It was awesome... but your girl has to be down for a third world adventure rather than 5 star hotels.
cape may,block island...presumptuous,though,to think everybody has the free time and disposable income to commit and spend,so if everyone is that wealthy,do it.or pay everyone's travel and lodging yourself.
otherwise...just get married when and where the people you both really want there can do it without sacrifice.it's not about the party,though,and it's not about your invitees,it's about you and your bride...when i saw her walk down the aisle she was so beautiful,we just had a pretty brief reception and then we just wanted to get away,were out of there before dark and spent like a week alone on our honeymoon enjoying being together in cape may and then on block island...it was awesome...no woman would ever complain about cape may or block island,though,and they have a lot better waves than at a broncos game.
Though I didn't get to go, two of my friends did Cabo a few years back. It's pretty cheap (a lot cheaper for them since they live in San Diego) and people who aren't into surfing still wanted to come along. Everyone seemed to have an awesome time.
