How to plan for Colossus of the Drylands in 3-4 sessions ?

Hey !

So I will be running Colossus of the Drylands in a few weeks for 4 players.
But they have a length requirements, no more than session 0 + 4 sessions.

After looking through the frame, I am wondering how to structure a story arc to fit into this timeframe.

For context, this group already played a 3 session Beast Feast, but it was easier to mostly improvise there.

I was wondering if I should already plan for only 2 hunts ?

And also welcoming any feedback from people who GMed this frame !
Thanks !
