Here is my opinion on the sweating issue...
all 8 of us had our faces done... 4 adults, 5 kids...
me, sis in law and niece are the only ones who made it home looking at all like we were supposed to!
My hub and bro sweat too much apparently cuz it was just running down their faces.... they had to go to the bathroom within half an hour of having it done adn wash it off!
My then 9 yr old ds was pretty ok, till his face itched from the sweat, adn when he touched it, it came off....
My then 5 yr old ds was ok, until we went on Kali River Rapids... he got drenched and needless to say off to the bathroom we went to wash it off!
My then 2 yr old dd, was ok, until she rubbed it on her stroller, one of us or rubbed her eyes from being sleepy... then it came off!
If we do this again, it will be towards the end of the day.
For our family of 5, we spent just over 50$ which was fine, but to have it wiped/washed off of most of us within a couple hours was sad!
I have heard they do them at the boardwalk too, so maybe since that is planned for an evening this trip, the kids can do it again...
