I have a reservation next week. My check in is on friday 3:00 pm. Its necessary for me to be on the exact check in time? I have an event that day earlier on Fort, so I would love to do the check in maybe at 7-8 pm. Is this possible?

No. You can arriba latter

You can check in whenever it fits there schedule. We where actually running late, and gave them a courtesy that we'd be making it in a little later. A very nice staff and hotel, enjoy!

Of course you can check in later as per your schedule.
