Don't buy the ones in the parks, they are expensive- and heavy. You will end up carrying them....
We bought small mister fans at
Walmart for under $3 each. Don't have a picture but the were H20 brand and about palm size with a small compartment for water and a foamy fan at the end. And a caribenner clip also.
Now we did not think these would work very well but for the price we thought we would give them a try. We were very pleased to find the worked AWESOME!! The kids got alot of sprays out of them before they needed to be refilled and the single AA battery worked our whole trip. When they needed refill they just filled at a drinking fountian or asked for a cup of ice water filled the fan and drank the rest. We have used these fans for 2 trips to WDW and on a cruise. The kids just clipped them to their belt loop or on their bag.
We did buy one extra incase we lost one or one got broke, still have it in the original package because the original ones are still working so well.
Found them in the isle where the fans are near hardware. Have also seen them at drug stores too
