I asked my wife and daughter what they remember since i really don't have enough hair to use a blow dryer. My wife says that she remembers all the hotels having blow dryers. We did bring convertors for lap top,ipod recharge ,phone recharger, camera batteries with 5 of us there was always a fight for convertors, some hotels may have had one in the room but it was usually by the desk and not movable. Two different girls burnt out very expensive flat irons connecting to their outlets without convertors they just used a three prong adapter and supposedly switch a button on the iron which says 220v but didn;t work!! my daughters flat iron made clicking sound but never burnt out not using convertor and just changing to 220v lucky i guess
My wife said packing for each move was a *itch because the suitcases have to be out in the hall ready to go very early in the morning for disney to take them away. so she had to think what we needed for getting ready,shower,etc. clothes,valuables, because what ever didn't go with the bags ,you were stuck carrying around and as carry on at airport. usually the blow dryer didn't make the cut and they would just use the hotels blow dryer. as an aside, a warning airport security is wishy washy, they change and make up rules as they see fit. one has very little recourse. if a security person does not know or recognize what you are carrying they may take it away and i am sorry to say if they like what they see they "confiscate "it! my wife lost many make up items to female security people nail polish, mascara,foundation,deoderant etc. they even took away a few american books , really nothing you can or really want to do.Hard to replace what you lose because they do not carry same brands types.as the tour progressed one could always tell a travel day nobody looked quite the same so the dilemma is what to carry ,what to pack, We did not experience any valuables being taken such as ipods,computers,cameras,money i think they know not to cross that unwritten line. So let the packing vs. getting ready games begin!
i guess the short answer is bring convertors and a blow dryer just in case. Sorry about all the info but there are few small answers ;like China they are usually big.
