Some Recent Reviews


We toured many venues to find the right place for us. The venue was stunning and unique. Not at all like what a typical wedding place would be. It was whimsical and elegant with rustic charm. Our guests raved about our wedding day. Finally, the owner, Debbie was super kind and helpful. Her professionalism and attention to every detail helped make our big day the success that it was! A 5 STAR wedding venue! Sam Franklin Baltimore Maryland

If you want to fall in love, look no further. This was more than we were wishing for. And the owner never ceased to amaze us in her efforts to make our wedding the day we dreamed of having. You cannot go wrong here. Sue Blickenstaff, Carroll County

10 Stars out of 5. The word pleased with everything doesn't begin to cover our happiness. Steve N, Gettysburg PA
