I'm guessing you don't know how much extra wattage/power a microwave sucks?
It's already been established Pop does not allow microwaves in a room ~ for multiple reasons. That's why microwaves are provided in the food court.
The rule is there for a reason. Not for people to just say "eh, the rules don't apply to me, I'm going to do what I want anyway."![]()
Actually.... a microwave energy usage is about 700-1100 watts. Lets compare that to a hair dryer 1200-1875 watts. Should I not bring my hair dryer??? Will I blow a fuse?? lol

I have only heard a bunch of Dis posters say microwaves aren't allowed. Haven't seen anything from an official Disney website that microwaves aren't allowed in the rooms.
OP. I've realized Dis posters like to set their own rules. Quite frankly, I wouldn't give it too much weight unless you get it from the horses mouth.
