I have a wedding next month, and I'll be staying at a Sheraton on a Saturday night. I booked a club-level room, since it was almost the same price as a regular room.

Some plans just changed, and I may need to stay Friday as well. Currently, the club-level room is $40 more, and it's not worth it to me to pay an extra $40 for that.

Is it even possible to book the previous night with a non-club-level room, while keeping the club-level room for the second night? I'm guessing that the easiest thing to do would be to simply get a non-club-level room for both nights, but being on the club level would be nice, so I figured I'd check here first to see if anyone had any advice.
