The main park no, Galaxies Edge can be busy though.
The busiest park is by far Magic Kingdom. There are more people at Hollywood Studios now because of the new Star Wars park, and Andy's Backyard. But it is worth the people!
It can be but varies with day of week and time of day. We have found that Monday's around dinner time to close are much better than a Saturday afternoon.
Now it is with Galaxy edge.
