I’m assuming you’re talking about WEB Slingers? Avengers Campus is the name of the land and WEB Slingers is currently a very popular ride located in that land.
I wouldn’t go there first unless you’ll be at the very front of the crowd. When I did it first a few weeks ago I was at the very front and almost walked right on but when I got off the entire queue was full and it was probably an hour wait already. Don’t wait an hour at park opening. I honestly recommend paying for the LL especially if you’re going to be there on a less busy day when it will cost less (it tends to be $7 on Tuesday-Thursday, $12 on Monday and Friday, and $15 on weekends)
