Note to self: remember the phrase “Manager On Duty” if everything goes south at a Disney hotel…
Along this line of thought, you should receive an email on check in day from the Resort General Manager, welcoming you to the hotel. In that email, there will be a blue button that says "provide feedback" or something similar. At the end of the email, the manager asks you to use that button to contact her if anything needs attention during your stay.
I used it at Beach Club last month. When we checked in, our first room did not have the bedding setup we needed and so I had to get us moved to a different room. No big deal, and they were able to accommodate us.
However, that next room had exactly two functioning outlets in it (the one next to the bathroom and the one next to the coffee maker). Every single built in one would not hold plugs at all (they'd just fall out) and had broken USB slots and the wall outlets were all loose/wobbly to the point where the plug would disappear INTO the wall as you tried to plug things in. Given the number of devices and magic bands we needed to charge up every night, this was not going to work. I used the button to "complain" about the broken outlets and the next morning, there was a knock at 8am from a maintenance man ready to change out ALL our outlets. I asked him politely to come back in 2 hours and he was in our room upon returning from our afternoon grocery run. Turns out he had to REALLY remove the old wall outlets and replace them entirely, requiring turning off power to our room completely. In the end, it took him 2 hours to do this job (although only 30 minutes after we arrived back, he was done). And voila, functioning outlets. We also noticed the toilet was leaking and they fixed that too.
I received a call from the maintenance manager later that afternoon making sure everything now worked properly.
While I was initially REALLY annoyed at how a resort room that had JUST been fully refurbished had such old and broken outlets in it, the response from that email was swift and satisfactory.
I have heard similar stories about this email feedback feature.
If course, if you need immediate help, the front desk is best. You can always ask to speak to the Resort General Manager as a last ditch attempt if all else fails.
