Answer: JUST IN CASE

As mentioned in the flavortext, you should follow each plan step-by-step, but as soon as a step doesn't work, ignore it and move on to the next plan.

Each plan starts by having solvers note one letter from the surroundings. Taking those letters together, you get the phrase `COUNT UNUSED STEPS`.

In plans A–P, count the number of unused steps per plan. Convert those to letters, using 1=A, 2=B, etc., to get the phrase `ANSWER JUST IN CASE`. The runaround answer is therefore `JUST IN CASE`.
