Reviews and reputation, per property
Volume, recency, and the specific stories a stranger reads at 11pm.
A system for asking the right slip holder at the right moment (after launch day, after a service job), so reviews arrive steadily rather than in one burst. Measured against every marina on the lake on volume, rating, and recency, property by property, because the lowest-rated marina in a group sets the ceiling for the brand. Reviews are also one of the things assistants read before they name anyone, so this proof works twice.
