Ok, as crazy as this sounds I just booked less than 2 weeks ago and now I am regretting only booking for 4 nights =(

I know the airline penalties involved (yikes) but what about the hotel?

What if you are there already and decide to stay an extra night? Do they just charge you the going rate? What if you booked through another company?

Geez, I can't believe I booked 4 nights, really, really regretting it!!!
