we will be in WDW the 3rd week of Sept. We arrive on a SUnday and would like to go the MK but is it as crowded on Saturdays? What are the crowds like on SUndays?
You should have no problem going on Sunday the 3rd week in Sept. since the parks are really not crowded during Sept. at all. But you may want to check the MK's hours since typically during the slower times the MK and AK close early, so depending on your arrival time it maybe better to choose another park.
