Isn't D2 Summit now just as big as The Summit since D2 fills the entire All-Star Resort as well as parts of Pop Century/Coronado Springs/Caribbean Beach?The big cheer competition is the first weekend of May.
The competition on the second weekend (your weekend) is for D2 and is much smaller in scale. There should be no impact to the parks at all from that one.

) day at Disney is better than a day at home...especially a day at home at work! Totally agree with going in not expecting low crowds too. Even though we're used to relatively lower(ish) crowds on our yearly September trip, every year now we tell ourselves the secret is out and it's going to be packed!
