Test whether your Disney Plan B really changes the problem
Compare what your first choice and fallback both depend on before calling either a backup.
Start with a failed assumption
A fallback can have a different name while still relying on the same thing. Moving from one outdoor activity to another may not address the condition that made the first choice unsuitable. Replacing one transport connection with another may still leave a journey that exceeds your group’s walking tolerance. The useful comparison is between dependencies, not labels.
Record the dependencies before the scenario
Write one primary option and one fallback. In the Plan B lab, mark weather, transport, admission, reservation and energy only when your choice relies on them. An empty checklist is not evidence that a choice has no constraints. If you are unsure about a condition, verify it before relying on the result. Keep special conditions in the commitment or trigger text rather than silently assuming they are covered by the five categories.
Test more than one change
Turn on a single change first. Read whether it affects the primary option, the fallback or both. Then combine changes that could matter together: transport and energy, for example. The tool reports intersections in your entries; it does not estimate the chance of disruption or recommend that an option is safe. A fallback exposed to the selected change needs a different assumption, a different choice or a decision to stop.
Use a concrete rehearsal
Example: your primary choice and fallback both include a journey your party may no longer want to make. Mark energy on both options and run the energy scenario. The result should say the fallback remains exposed. Change the fallback only after reviewing the real alternative. This is a fictional reasoning exercise, not a statement about a particular Disney route.
Decide what an unresolved result means
Do not collect backup names just to fill the page. If no workable alternative is confirmed, record who will make the call and where you will obtain current information. Keep the option to shorten the day. Recheck the result whenever the group, destination, service or booking changes.
Try this with your own choices
The lab checks the entries you provide. Verify the actual conditions before acting, and review the plan after a change.
