With a few modules, my group did Hallows Last Hope in one 5 hour session, Crown of the Kobold King in 4 sessions, Revenge of the Kobold King in 2 sessions, and Hungry are the Dead in 7 Sessions (they met with some difficulty in Hungry are the Dead)!

I am currently playing my character Cyrino through Carrion hill with 4 others and we are about to begin the 5th session.

Honestly it all depends on the group, either way we're having fun during these adventures!

Im currently in prep for Carnival of Tears in which ill run once we're done with Carrion Hill. I'm hoping my players will have it done between 3 - 5 sessions!

Keep those dice rolling all!
