Unfortunately, no. Guene Estates is a historical venue and has strict guidelines on outside food and drinks. We have in fact thought about this and will have an open bar and plenty of food.
We only have the venue for 6 hours so at 11pm we are required to be off the pavilion and chapel area by 11pm. We did get the house and cabin for the night. You just are not permitted on the pavilion after 11pm.
