“We will, no doubt, come back any time we need to host a formal gathering and refer our friends and colleagues as well. Ultimately, all we were expecting was a nice location to hold a surprise party for our father’s 70th birthday. We ended up with much more: a memorable, lasting experience he will treasure for the rest of his days.”
