IF they willing to help they can let you in early and MAYBE even without additional charges.. But technically if you check in before their check-in time, then of course you stay only until noon(i think their time is 15:00, super unfair).So to spend a night in your situation you'll have to pay two days.
Ask for an early check-in. If rooms are available, most hotels will accommodate.
U should have til tomorrow at checkout all depends on how u set it up at check-in
