I have found capacity numbers of about 75k for HWS and
Disneyland at about 80k, You are right in the fact that there are alot more rides at DL to absorb the crowded feeling, and yes because of lack of rides you will Defiantly feel the crowds more at DHS, but I do agree we should move this topic to the other thread, as comparing these parks is hard enough since they each have unique management requirements.
There's no way I buy 75K as DHS capacity - unless all we are talking about is how many people could be crammed into the volume of the park.
Total daily rider capacity (Including ALL shows and this includes Fantasmic!) in a 13 hour day (9 AM to 10 PM) at DHS is only 142,000 riders/viewers at DHS. That would mean 75,000 people would on average get to do TWO attractions in a 13 hour day.
Total daily rider capacity in a 14 hour day (9 AM to 11 PM) at MK is 346,000 riders - almost triple.
Disneyland is somewhere near 500,000 riders per day.
So if you want to argue the parks can HOLD the same number of people - I guess so - as long as all those people don't mind just standing around in a crowd doing nothing. Physical capacity is different from what a park is capable of handling.
And let's also consider how many people are actually there. Using 2017 numbers, the average daily attendance was 29,400 people - and again realizing that all those people are likely not in the park at the same time. MK was 56,000 people each day. (DL was 50,000) The question is what do we see happen at DHS. Does the attendance DOUBLE? That seems unlikely as it would have to surge higher than MK - but I could see a 50% surge as being possible - let's say 45,000. That's still less than CURRENT DL numbers. But can the park HANDLE that? Even with the extra capacity from the 3 new rides (say 60,000 riders per day) that means it's only 4 attractions per 13 hour day is possible. This means likely 3-4 hour rides ALL ACROSS DHS.
DL currently sees 50,000 - and assume a similar surge of around 15,000 people to 65,000 - that's in a park with 500,000 riders per day. That means you can still ride 10 rides per day. So while you will see massive lines for the Star Wars rides, there's a good chance the other rides will only see 10-15 minute increases.
In other words, DL is MUCH more able to handle the influx of visitors from a ride capacity standpoint than DHS.
