See, your first problem was not getting him to agree to take you away to good places before you got married.
I promised that I would live and die in the town in which DH was born/raised. He promised to take me away to good places several times per year. He never traveled before he met me.
He doesn't like living up to his end of the bargain, but has fun when we're away and he's very well traveled now. You should here him give travel advice when someone asks what to see or where to eat in various places. We're actually toying with either Hawaii or London for next year's big trip.
Last summer, I was able to book 6 days & 5 nights at the Majestic Colonial in Punta Cana for about $800 per person. That included the flights, lodging, transfers, hurricane insurance and all meals and drinks. The resort was very nice. The food was good and plentiful as were the drinks. Our kids had a blast and my parents and sister came with us.
You'd be hard pressed during the summer to find something in Cape May for a similar price with meals, plus, there's no substitute for the azure waters of the caribbean.
So, my suggestion is to give him some xanax and get him on a plane to the Dominican Republic. Call it a second honeymoon... whatever you need to do to get him to go.
Good luck in getting him "outa Dodge."
Actually, if you can't get him to DR, my next suggestion would be Ogunquit, ME. We went there for 7 years straight for a week at a time. The restaurants are wonderful. The beaches are clean. It's a very family-oriented environment. There is a large gay community there, so don't choose Ogunquit if your DH has problems with that. Things are laid back and while you'll be able to identify the gay and lesbian couples, my kids never even noticed that some of the couples were not male/female.
