I didn't find it too hot. It was adequate. It wasn't wonderful. It wasn't horrible. Does my hair dryer from home work better, yes! Does the Disney dryer work as well as other hair dryer in hotels, probably. I used it twice. I did bring mine from home. When crunched for time, I used mine from home. When we had plenty of time, I used theirs.
But also keep in mind, I hate drying my hair! I dry it for 5-6 minutes tops. Wherever it is at that point, it's done.
