The attractions I don't think are going to be the biggest problem. Considering there are so many new things, the increase will eventually spread out through the parks.
However, the problem is going to be finding places to eat. That's going to be brutal. Quick Service restaurants (especially in the parks) will be more slammed than they already are and getting ADRs for table service will be harder to get than fast passes.
