A booking is confirmed only if the permit for that city covers every night of it — or you have checked that the city needs none. A permit that runs out on the Tuesday of a Monday-to-Saturday run does not cover the run.
The city, the kind of permit or card, who issues it, the day it runs out, what renewing costs, how many days renewing takes, and how it is done. Never the permit number, never your legal name, never a picture of the card — you carry the card itself.
Each renewal has a day to start by: the day it runs out, less the days that city takes, less a week of margin for getting there. The ones with a booking behind them come first.
