I've come down with the flu a couple days into a trip before. That was horrible. I kept going, tho, after a trip off property to a pharmacy. I generally bring a 1st aid kit that includes cleansing wipes, bandaids, blister pads, and neosporin. This has come in handy when one of the kids fell and skinned a knee. I even got complimented by another mom for my level of preparedness. LOL! I pack sinus meds, cold meds, travel kleenex, travel size baby wipes, advil, my son's allergy eye drops, and a supply of any other prescription meds we may be on at the time. No matter how well you plan, tho, sometimes things come up. In May when the hubby and I went without the kids I misjudged how much Dove bar soap I'd need (I have very sensitive skin), I should have brought two bars. Also, hubby was less than halfway thru a 6 week course of very, very strong antibiotics while there and had some secondary problems from the meds. If you ever need anything over the counter or that can be bought in a basic drug store go to the front desk of your resort and they can get what you need for you. They have a local drugstore that they work with to take care of these needs. Basically, the order is called into Turner Drugstore and they will deliver it to the resort within a few hours. I think they charged the cost of the order to our room. What a lifesaver for us!
