we just went to wdw june 1-6 and we did not come home sick....we used purell after EVERY ride and washed our hands before we ate...even my 3 yr old...she even knows not to put her hands in her mouth,not to touch hand rails and not to touch the public potty before one of us cleans it off with a wipe! We didnt get sick at all..we kept the gel in our pocket so we didnt forget to use it and dd knew to wash her hands when we went to the bathroom.I DID see alot of people that were coughing and some kids with snotty noses but we didnt CATCH anything.We also cleaned our room ourselves and I sprayed down our room with lysol when we checked in.
