Hello, I am interested in having my wedding at Promontory Point, a historic site in Chicago. The site director said that we HAVE to use vendors from their preferred vendors list, has anyone ever had their wedding here and if so, did all of your vendors come from their preferred vendors list, Please Help! I want a different caterer but they said I could not have the caterer I wanted because it did not come from their preferred vendors list. If anyone has not used a preferred vendor for your wedding at PP where there any consequences.
