Ugh, that would be a total nightmare for me. How/where do you research to find out when they will be there?
15's are there January & February nonstop and during our summer break. There is no break from their behavior 24/7.
For Cheers these are some competition dates, this will not account for days before and after for fun days. At resort my experience has been the cheer practice that runs late, in that case go to the front desk (in person) and complain so they stop, they fill the food courts but no more than an other time when the resort if full and I have never had issues with them on buses and in the parks. They are there mostly to compete. Their packages are primarily All Stars, Caribbean Beach Resort and some POP. They might be found at POR and CSR but not usually or many.
