We haven't had mosquito issues either - and we spend a lot of time outside at the Fort when we go. I did, however, have some kind of bug (I still don't know what, we think maybe a water bug, but I smashed it before I could see it) crawl in my ear one morning WHILE I was in the RV! It was still dark and in my half sleep I grabbed it in and smashed it. But it did FREAK me out! I did NOT go back to sleep that morning!!! (Hazards of camping, of course. Disney can't get rid of every critter, nor would I want them to!)
