I have researched bats indigenous of New England and I can't find a bat that has a wingspan of even close to 2 feet.
I don't doubt your encounter and wonder if it could be an bio-ecological migration taken place due to the "white nose disease". I'm not a scientist and unfortunately didn't sleep at a Holiday Inn last night.
Please remember folks that bats eat mosquitoes and although they are yucky, they help us prevent Eastern equine encephalitis virus, as well as many human diseases like Lyme disease.
