We just charge a flat rate with shoes included. We do $5 / person or $25 for a whole hour for larger groups. Wanted to take some of the advanced calculus out of the price of bowling, yknow?
My local bowling alley charges $130 for shoes and 1 hour of bowling for 4 people off-peak. That scales up to $220 peak rates (e.g. Saturday night). It’s in the middle of a major city so it’s a different market of course, but the pricing difference is striking. No pun intended.
