I do not travel very often so I don't know how the check-in process will go. My flight gets in at 11:40am on a Monday. I have arranged shuttle service from the airport to the Strip. Can I go to the Signature and check in and leave my luggage there, even if it's not official check-in time yet? Likewise, on Friday, I assume check-out is at 11am, but my flight home isn't until 4pm. Can I leave my luggage at The Signature until I go to the airport?
