I think I saw that thread too, but can’t find it.There was another thread asking about this fairly recently. I can’t find it right now.
You can certainly ask but I’d be prepared with an alternate plan in case it can’t be accommodated. If you need to prepare food in your room, you should reserve a room type including a kitchenette. There may be fire code rules against cooking (microwaves, toasters, hot plates, etc.) in standard hotel rooms that weren’t designed to include such devices.
Unfortunately, my ability to eat is severely limited due to a plethora of medical conditions. Is it possible to request a microwave at a deluxe hotel?
All the WDW DVC have microwaves. You could rent points and stay DVC.
So as an FYI there is a hot discussion in the DVC threads as the new VGF2 builds do not have microwaves in the studios.
