You’ve gotten some great advice, and I agree that there are Copper Creek studios on all floors. Unfortunately there are more of them on the ground floor. We prefer and request higher floors as well.
The maps
here show the floor by floor layouts of the Copper Creek Rooms. The smaller rooms are studios (which are the width of one hotel room, except the alternate studios which are in some corners.) The dashed lines indicate lockoff rooms, where a studio is next to a 1 bedroom with a connecting door.
Yep, every floor has dedicated studios, but the alternate studios are lockoffs with the room next door. On the declaration floor plans you can see the double swing doors, and I have noticed them in videos of the alternate studios too.

The x119 rooms are dedicated studios right next door though and are on floors 2-7. x121 rooms are just around the corner on the other side of the mid-wing elevator lobby and are on floors 2-6.
