Long weekend away

Hi ladies, I need your help with something NWR. My mom and I are looking to do a long weekend away at the end of July. We want to go somewhere within driving distance of NY. I have done some online research, but it is hard to know what is really good. So many places are very expensive or require a 3 night minimum in the summer. We were looking to go for 2 nights. I would like to spend no more than $150 a night.

I am very open. I have looked into Martha's Vineyard, Providence, the Catskills, Lake George, the Hamptons, Fire Island, Baltimore Harbor, and the Jersey Shore (which I don't know what towns are good).

Any recommendations/suggestions?
