Start by collecting the basics from the last six to twelve months of lane activity. Record the reservation time alongside the actual lane start time; this shows how far in advance people book and reveals the time-slots most likely to suffer no-shows. Next, note when each group checks in and when they leave—that simple pair of timestamps tells you how long sessions really last and where overruns occur. Add the size of every party and the kind of visit—walk-in, member session, rental, or class—so you can see which guests occupy lanes the longest. Finally, mark each booking as “showed” or “missed,” and if it was cancelled, jot down when that happened. These four pieces of information, kept in one clean spreadsheet, will give you all the insight you need without drowning you in technical language.
