Welcome!! A couple of things…
FYI – A common misconception about Touring Plans Crowd Levels is that they are an indicator of the number of people in each park. However, they are an indicator of average queue waits at the rides in that park during 11am – 5pm .
A CL 1 can feel like a CL 4 in terms of park capacity, but the queues may be moving quickly. Conversely, you can be in a CL 9 park that feels like a CL 5 because the streets aren’t packed. However, all the queues are super long.
Touring Plans typically uses the previous year’s results to set the CLs for the next. However, they set them 365 in advance and don’t really update them until about 90 - 60 days out. You might see a small update here or there, but IME do not base your travel plans that far out on CLs.
Keep doing your research and see what events took place not only last year (COVID) and coming next year, but also 2018 / 2019.
IMHO - In 2021…so many people were still homeschooling and just ready to go out after a long 2020 that the parks were swapped. That along with labor shortages really made queue packed = high CLs for 2022.
