Yeah, the amount of soda that the mugs hold is quite ridiculous. However, I got filled up at the Food Court and then took another cup of it to the room with me. It really does make a big difference what building you're in too - I was all the way in Broadway, and had to walk all the way to the room when I got home from a long day at the parks, all the way to the Food Court to get something to takemy medication with, and then alllll the way back to the room. Oh well....
