Yes, they will do this!
Last year while staying at Caribbean Beach resort (which we LOVED) we were having dinner at the Grand Floridian and my DH asked to see a room there because we were considering staying there on a future trip. A very lovely CM from the Front Desk took us to see a room and my DH liked the resort and the room so much that we switched resorts that very night!

He told them that as long as they had a room with a view of the castle, we would switch. The CM made a couple of phone calls and within 2 hours we were checked out of CBR, into GF and swimming in the GF pool
While we were staying at the GF, we were having dinner at the Polynesian and asked to see a room there. Another nice CM from the Front Desk showed us a room, and NO, we didn't switch from the GF to the Polynesian

but now DSs want to stay there next!
As long as they are not busy checking in guests, they will show you a room at the resort. Let them know you are considering staying there on a future trip and would like to see a room.
Happy resort touring!!!!!!
