You should call them, I called because I was going to be late on Thanksgiving day and the front desk said I can check in anytime before midnight so i arrived at 8pm with no problems. And check out is at 12 because the keys demagnitize at 12 but you can get a late check out at 1pm
I think the check in time is around 3PM, but if they have rooms available you can check in early sometimes.
