We have been to Pop, CSR, and POFQ and never had anything when we got there. Mousekeeping will decorate with the things you buy throughout the week sometimes-at POP everyday they would put all DS things he had bought in different places. One time they were hanging from the curtains and in the windows, another day his stuffed Mickey was watching TV.
Last trip he had bought a rubber snake from Rainforest and I got a voicemail from the housekeeping office asking us to put it up or the housekeeper would not clean our room. I thought that was quite rude-it was obviously a rubber snake that they sell on Disney property-but whatever. That was my only complaint about POFQ-I think the housekeeper should have been told to get over it-Im the guest and my son likes rubber snakes.
