My protag is attending a writing retreat, so I had to decide how long it would last. A weekend seemed too short for all the activities I have planned (there's a murder, a missing body, hauntings, and other odd events), so I'm going with a week. I'm still behind on my prep work, so I haven't actually started my timeline yet, but when I do, I will be labeling what happens on each day of the week so I don't over-pack the days, or spread them out in a stupid fashion. In the past I've further broken down what happens on each day, minute-by-minute, for a story that takes place over a shorter time period. Just do whatever works best for you to keep things consistent.
