YES-- It is the Varsity ALL STAR Cheerleader Nationals (not the high school or college teams). We will be competing at MGM and WWoS on Sat/Sun the 10th and 11th. I would stay away from MGM on those days but I think you will be fine otherwise.
I think most of the Cheerleaders are staying at the All Star Sports. Our team will be at the ASMo from the 8-11th and then my DD(10) and I will move to the POFQ from the 11-14th !!! IT will be nice to have some peace and quiet.
I also heard there is a big convention at CSR and the YC because we tried to get rooms there and they were sold out over 3 months ago
Good Luck and Have a great vacation!!!
