I was fairly overwhelmed by the prospect at first, but this week had the brainwave to create an interactive twine board which will allow one to click on the corresponding door that the party is pursuing and not lose track of your potential movements/Strahd movements as you are doing so. In a lovely, bittersweet sort of way, I am finally prepared to run my last session of Curse of Strahd with my current group, which comes with the pain of prepping parts of Ravenloft I had not already prepped in a previous short jaunt to the Castle the party took early on.
