It is not impossible,but it is difficult for sun-thurs from June-July. We tried first time in 2002 and was lucky to get 4 nights in 2bdroom. Next year, we could not get any thing so we bought add-on there to have 11 month window for summer. We decided in Jan to try for summer(so much for having the 11 month window, if you don't plan early enough)so this year we got 1bdroom for august12-15 and we had a great cm in members services, who looked for any sun-thurs 3 nights from june 6;he went week by week until we got the august dates. Previously, June and July have been very humid and hot, but this year and last, year we lucked out with 80's and less humidity..great beach weather. It is harder to get studios as there are fewer of them but we always get at least a 1bdroom; 2bdrooms are the easiest.
