No, it was one reservation. However, last night was at a lower rate. I've had many reservations where there are different rates on different nights. When making the reservation at Marriott.com a notation comes up in red that "the rate for this room changes to $XXX on X/X/XX".

This is the second time I have received a bill at this property after 1 night, but the other time it was not a problem keeping me in the same room. I just needed to have my keys reset.

It was a 'Stay 3 and save' rate (I stay on that code a lot), and they often charge a 1 night deposit a couple weeks out. I noticed that for this reservation they charged my credit card for all 4 nights about a month ago. My bill this morning showed a credit balance for the next 3 nights 'deposit'. That just makes me even more upset, not only did they kick me out of my room, they kicked me out of a room I had already paid for.....

No upgrades here. Just the room type I reserved.
