Hi Amanda!
2 places I can think of to have it would be at Seven Springs or Hidden Valley in south-central Pennsylvania. you take I-70 to Breezewood, then get on the PA turnpike and they are both off exit 10. Seven Springs I've seen the cottages - about 8 people can fit in them and they are cute as anything. They might be a little pricy though. Hidden Valley probably has something similar but might be a little cheaper.
