Poconos is the spot. I ve spent some time at Lake Harmony near Jack Frost/Big Boulder. I absolutely love it up there. It s only about an hr and a half from lansdale. You could probably find a cabin available on craigslist.
PA is a great place for nice and quiet! I would look on craigslist for anyone that is renting out a cabin for that time frame. If you can find a place in one of the state forests you can have an awesome vacation.
Go to the Poconos. They are very scenic and beautiful. They are one of my favorite places in PA.http://www.800poconos.com
I m not sure how far you are from the Poconos but that is the ULTIMATE place to go with a spouse. There should be a website....check it out.
