I finally get to spend a night at the Plaza (as part of my goal to stay everywhere at least once), though it's only for one night at the beginning of my trip. According to the confirmation email, check in time is at 4 PM. I'm sure I can show up before then; but do they charge an early check in fee? I'd like to catch a morning flight and not have to spend time wandering FSE before checking in. Oh, and it would be on a Sunday, if that makes a difference.
