I need a great vacation spot in New England?

I live in Connecticut. My boyfriend and I want to take a trip to somewhere in New England in the month of October. We need a relaxing place so we won’t be hiking or anything like that. We want to site see and just have a nice weekend. I’ve looked at a lot of peoples questions about vacationing in New England and I don’t want to go to Cape Cod. I just want to relax in a nice resort ( that’s kind of inexpensive) with an indoor pool, plenty of stores around, shopping…. If you can give me a bunch of ideas I’d appreciate it. Also, since that’s around halloween time I’d like to do some Octoberfest things or scary attractions. Not six flags or anything in CT or Salem MA. Thank you
