Used to work in New Haven hotels - it won’t be too bad if your venue has parking, that’s by far the biggest hurdle! I’d look at some of the hotels in Milford/Orange/Branford for blocks - otherwise you’re gonna see some insane rates in New Haven proper. Let your vendors and guests know to plan for some other traffic, and book your rehearsal dinner venue soon! Let me know if you have any other questions & need help navigating. Congratulations!!
