One group, one route, one sequence
A crew that must remain together under escort cannot use the usual approach of splitting across areas. Everything is sequential, which means the route has to be planned to avoid backtracking and the task order has to be efficient. A poorly planned route can waste a third of the available time in movement alone, which nobody notices because it looks like work.
Planning the route once, at mobilisation, and recording it is worth doing properly. It also gives the escort a predictable pattern, which shortens the process for them. Where a route has to change because an area is unavailable, having a documented alternative means the decision is made in advance rather than negotiated in a corridor. Recording the route in the proposal also gives the site something to review, since they may know of a shorter path a visitor would not find.
