Did you go to Methacton? My parents live in Trooper and I went to Methacton.
We were married in Bryn Mawr at the church my parents were married and then had our reception at the Merion Cricket Club last year.
If you are getting married in the summer you may have more flexible pricing as it's a slower time.
I would check the hotel across from the Acme in KOP, I forget the name but a girl her was married there last year.
Also Normandy Farms does summer deals, Audubon House/ Sanctuary I forget what it's called, Westover CC.
