Hi! This is my first post on FT. I've been a member for a while and have come here when I've had a question about flying/traveling (Thanks to all who helped this lurker

I searched and searched but couldn't find a post on this topic, so please forgive me if the answer was right under my nose and I missed it... Anyhoo, here's my question (and I used some/all/different pairings of the following as keywords)..

I booked a Crowne Plaza hotel for a Thursday night (two people) . I want to stay Fri. and Sat night also but there is no availability. Can the hotel kick me out Friday morning? Or can I just say I AiN'T LeaViN till Sunday? Does the hotel have any obligation to accomodate me? Will they oblige me out of the kindness of their heart since I'm already there even tho they are booked? Or do I have to go find another place to hang my hat for the remaining unbooked 2 days?

BTW...all their properties are fully booked that weekend. I guess I'm lucky to have at least gotten the one night.
Thank you in advance. I hope I can find my way back here. I'll check my messages here if anyone cares to respond that way.
Thanks again JP
