These posts show how subjective this “crowded” really is. These posters were there at about the same time. One found the crowds better than September, one found them much worse. Expect crowds, that is just the reality of WDW now. Make a plan & have realistic expectations. I think your expectations play a part in how much you end up enjoying your vacation. If you go in thinking you’ll have low crowds & it ends up crazy crowded, you will be frustrated & disappointed. If you go in expecting it to be crowded but you get things you planned done, you will be much happier in the end.
