I mean sure, you could request it. Probably won’t happen though.
I did however make a request for a hotel one time. It was at a Hampton Inn. When you make the booking, it asks for special requests. I asked for a picture of “Carlton” from the Fresh Prince of Bel AIre as a joke. Totally forgot about it. When I got to the room, there was a picture of Alfonso Ribeiro (the guy who played Carlton) on the nightstand. So, sometimes requests can be honored.
I’m almost embarrassed to tell that story though. Almost. Luckily, I don’t embarrass very easily.
This was not at WDW, but I once requested a miniature pillow and blanket + a cookie for my wife as a joke and upon arriving at our room, there it was - what looked like a small children’s blanket and pillow on one side of our bed and a cookie on the night stand. She was not amused but pretty happy about the cookie. Needless to say, I was the one who slept in the tiny linens.
