I've had a tangentially related question for a while. Thought it would be ok in this thread.
When the chairs are tagged, does that mean the chairs are yours to use all day? For example, if we go to Perch for a drink or lunch, will the chairs be taken?

Also, while I'm at it, we'll be there(Mt.Vernon) for Christmas and New Years. What time in the morning should we plan to find the perfect chairs at Club O?
