We're in PA too!Yes, Stay More Save More, if you're going for more than a few days, is generally better than APH rates....Even though we live in Pennsylvania, we get Annual Passes. You can't beat the rates if you're on a fairly long vacation.
Buying AP for all of us doesn't work - can't justify the $100 more per person as we won't be going more than once this year. But, what I'm looking at is maybe buying an AP for one of us to benefit from the discounts in the parks/restaurants.
