I have solved the problem! I talked to technical support and they looked at my plan. The person said those rooms must have been assigned a different style of room or name. She had me delete the hallway wall that connects to the rooms, then delete any wall that would open up the hotel interior rooms to the hallway. This then matched the settings in the hotel rooms to the hallway. I then saved the program, closed out, reopened the program, and rebuilt the walls. The floor is now there and all the walls look normal.
