Cape Cod/mv seeking inspiration

With our original wedding plans all thrown out the window, my fiance and I are thinking of eloping this summer in most likely Martha's Vineyard. We're both from MA so we think the safest yet still magical place for an elopement would be down the Cape. The idea is that it would be fun to splurge on a romantic weekend away. I've never been to the Cape so I would love recommendations for ceremony locations, lodging, local tips, photographers, officiants, etc.
