The dates you are taking about are high school cheer. So school groups - with team travel rules. Not the Summit (competitive aka club cheer) later in the spring.
Checking the varsity website it is ASmusic, ASsports, POP and CSR resort.
I really don’t think the noise level would be much more, than in the summer when the resort is filled with children. You will feel it in the food courts. But the practice times, different size and type group competitions are all so different. It’s not like everyone competing at the same time.
