WEnt the last 4 JUNES and last August and while they are THERE we never had a problem. However I stay Deluxe to ensure we don't see massive groups at our hotel. One thing I noticed this past June that I liked, there were two large brazilian tour groups but they were being led by Disney Cast Members. It seemed way more organized to me. We did stay ahead of them to avoid running into the fast pass line with them but the cast members directed them, waited for them and basically herded them along. I thought that was a super idea....
