I teach Kindergarten and I am neurotic about handwashing. And in a pinch, hand sanitizing....though I admit in the midst of a sickness in school, I do both!
Before my first (non Disney) cruise a few summers ago, a veteran cruiser friend gave me a few tips that made me feel better...and frankly they are probably good for any time, not just cruising!
When you get to your room, take out the container of Clorox wipes that you have brought with you and wipe down all the surfaces, doorknobs, sink handles, phones, remotes etc. In theory, the rooms are cleaned before you board but in practice, are they sanitizing? Not positive. (I actually do this when I get to a hotel, too)
Use the hand sanitizer they put at the beginning of the buffet line (I hope they do this on
DCL...they did on Carnival)
At the buffet, use a napkin to pick up the serving utensils. (yes, you might get strange looks...but if people realize why you are doing it, they might think you are smart and do the same thing!)
Also, take food from the back of the plate not the front.
When you get back to your seat, sanitize your hands again (or wash them in the bathroom)
When you leave a bathroom, use a tissue to open the door. Again, Carnival provided tissues by the door and a wastebasket on the other side. I thought that was genius!
Wash your hands before you eat. This includes before making that soft serve cone as you pass the machine (do they have these on Disney?)
When you are ready to eat in the main dining room, if you have touched a menu that will be returned, wash your hands (hand sanitizer)
Menus are touched by many (unclean) hands!
These all sound OCDish, I know! Spending my day with 5 year olds, I can tell you,their hands are in places they shouldn't be!! Being neurotic about handsanitizer on a cruise might sound crazy but could keep you from getting sick!
Basically, wash your hands, wash your hands, wash your hands! And don't put them in your eyes,nose or mouth!!
