I suspect there are a larger number of disboard members or future members who mainly frequent the boards for a relatively short time period before a visit to WDW. This will produce poll results that will probably slide for a while. The poll may actually give a good indication of how the crowds differ over the course of the year but not any time soon. For example, it appears from poll results at the moment that January/February is a more crowded time at WDW than June/July.
We plan to stay at POP Century at the end of May for at least 8 nights. Visiting in May because we will be visiting with family that has to wait for school to end (son is a teacher).
We plan to visit in September on our own and take advantage of low crowds. Probably 6 or 7 nights; maybe stay at Poly.
