We once brought 2 candels with us when we stayed at AKL (last time we were there)...we had them going one night and took them out to the balcony to blow out, no problems with anything...then, two days later (while we were still staying at AKL) we got back to our room one night after being in the parks and there was a message on our phone saying "our house cleaning staff has noticed that there are two candels in your room. We ask that you do not light them durring your stay with us. Disney resort hotels consider them to be a fire hazzard and we ask that our guests do not use them durring their stay with us. Thank you..." Then, later I heard from someone (when we were back from our trip) that people can receive a FINE for using them in their rooms? I don't know if this is true, and I don't know if it's different in hotel rooms or villas or what...A guy that works with my husband said "we just got back from staying at Disney and we had to pay a $XX (dollar amount) fine because we lit a candle in our room."
Like I said, I don't know if that's true...but make sure you call ahead or ask before you get a fine!!! I know that we were not aware of that "rule"
