Montauk Lighthouse wedding?

Hi...We checked out the Montauk lighthouse too and loved it. The only problem we had is that they didn't have a backup spot for rain.
Also...a lot of guests would have to have a 2-3 night minimum at hotels in the summer. Local RH's include Gurneys and Montauk Yacht Club. Montauk Manor is also nice, but they don't do summer weddings.
