Actually, after an hour or two, the bites no longer bother you - we were in HH in early March, 2000 and the only time I noticed them was at dusk on the porch - the only time at VB was also at dusk on the porch (in a rocking chair) - if you plan to be out at dusk, it wouldn't hurt to use SSS - especially for the campfire. Being from Florida, we have gotten used to mosquitos, but several years ago they had an encephalitis scare and Disney handed out warning sheets and everything - what was funny is that when we walked by the campfire, not even down near it, but just on the boardwalk, the smell of Off was so strong, I think the whole insect population headed down the beach for the night
