Has anyone heard of a venue charging a 20% overage fee, due 30 days in advance for "just in case" overages like increased guest count, upgraded package, etc? Our venue just surprised us with this as we were about to sign the contract and said it was a brand new policy just implemented (even though we asked for the contract 2 weeks prior and they took forever to give it to us). They say they will refund the 20% if no overages happen. I've never heard of this though and don't like how this was handled, nor do I agree with holding onto 20% extra for "just in case". Has anyone else seen this? BTW, this is a very famous, reputable national luxury hotel brand that's implementing this...
