So there are 3 straight weekends of Cheer. First Cheer Worlds is April 28-30, followed by the Summit May 5-7, and then the D2 Summit (1st year at WDW, last time was in Tampa) May 12-14. We went to Summit this last year and I would avoid all of the All Star Resorts as they are the main venues. Some stay at CBR as well as overflow into Pop. Most begin to arrive the Wednesday or Thursday before their competition and usually leave early to mid week following. We are from SoCal so we arrived Thursday and stayed till the following Saturday. Sunday night was a zoo as the competition was over and since this is the National Championships, many gyms dont allow their teams to go to parks until everything is over on Sunday night. They do a party at HS Sunday night which was crazy as was DTD for meals. Monday and Tuesday were decently busy at the parks, but nothing like a 10, maybe a 6-7. By Wednesday it as empty like a 4 or so until weekend crowd came on Friday. For most part if you avoid All Star resorts etc, you won't be impacted at all by the cheerleaders. For the most part all are extremely respectful as they are very disciplined kids, but always have exceptions to the rules. For sure nothing like the Brazilian groups or every Pop Warner football groups either. Hope this helps!!
