As you are going multiple nights I would give the Stay and Scream a go and see how it works for you. Fridays will be busy - there is no avoiding that, just so long as you are aware you should be able to plan around it.
The first night you go I would use the Simpsons area holding zone. They generally take you to the back of the park around Men in Black. Here you should be able to do 3 houses minimum - possibly 4 depending on how quickly the crowd moves through the park. After that use the park app to keep a check on queue times and hit another house accordingly. If you want to stay later use the time to enjoy the scare zones and show.
On the second night - provided its not a Friday - go to Finnegans holding zone as early as you can and try to get to the head of the queue that will release you to Stranger Things. If last year is anything to go by this will be the longest queue from the start of the night to the end and you shouldn't be surprised if you see times of greater than 3 hours. Do this house first then come out and head for the houses around the back of Jimmy Fallon. You may get 2 or 3 done before the queues start to grow.
The other holding zone they use is the Hello Kitty area for the house that is behind Shrek. Once you have done this one you can head over to Barnies play area and knock out a couple of the houses quickly as the exits normally lead to the entrance for another one.
Over the course of 3 nights we have easily done all the houses - then on return visits focused on our favourites.
