Perhaps it isn't the people who are distressed by the bugs who are missing the point!
If this is such an inherent problem in an area so dependent on tourism $$$$, then perhaps WDW [& Florida, in general] needs to be more proactive w/this problem. Why should tourists be expected to tolerate this situation, especially when paying such a premium for on-site resorts?
Here's a thought...
If they spray the grounds "every morning at sunrise" & only "the rooms often", perhaps the pests are running from the grounds into the rooms to avoid the bug spray.
I agree with the others who posted that no matter how many wonderful things are posted about Disney, any negative criticism about Disney seem to be frowned upon, and Disney defended. It is unfortunate, because it makes some people shy away from posting their negative experiences, which would help keep the info here more balanced.
