The nearest hotel is the Springhill Suites Brookhaven. We've reserved a block of 25 rooms there and it’s about a 10 min drive to the venue AKA casa Apfel. You can do that here: Book your group rate for The Apfel ~Scott Wedding
Way more fun idea: get together with some friends or family and rent a house in Bellport. Maybe check out our "places to go, things to do" page and find a location with those interests in mind. I just did a little searching on VRBO and saw a few options within walking distance of the wedding. Check it out!
