...will likely need a place to stay thursday night

we got a room for fri-sun in the holiday inn but don't know when we will get in on thursday night from cincy and don't really want to pay that much for another night

any suggestions? any floors? any parks/parking lots that will be safe to sleep a couple of hours?

also, does anyone know the earliest we can check in on friday at the hotel?

thanks in advance, i look forward to rocking with you all
