tl;dr: Schedule games with the knowledge that some of them will mostly likely fail and drop off - so that after that happens, you still have roughly the amount of gaming you want going on.
At one point this month my gaming schedule was ridiculous
- 15 sessions in 28 days - just over one every second day
- this was made up of a bunch of different campaigns
- Up from 13 in January
This has simmered down to 10, including replacements for some slots which is helpful but shows there were even higher cancellations that got back-filled.
For a while it was looking pretty frantic but it was just a good run without cancellations. Rapidly the pendulum swung the other way - two home campaign sessions scrubbed due to travel plans, a table of my drop in game due to scheduling, a sick child, miscommunications, etc.
The numbers plummetted and suddenly what had looked like an insane amount of gaming pruned itself right back.
