If you have a reservation that didn't require a specific number of nights, what happens if you decide to check out early? Are you just charged the amount you booked at for the nights stayed? Or does checking out early change the reservation and so you are charged the going rate for the number of nights stayed? I have 2 rooms at Excalibur booked for 5 nights in July. The rates and resort fees have increased since then - so if I change plans and decide not to stay there the whole trip, I would prefer to check out early, rather than cancel and re-book.
