30+ and 50+ also describe a course atmosphere
Dance schools use age labels for more than just grouping people by birthdays. A 30+ class may appeal to people who aren't looking for a class for teenagers. A 50+ class may bring together a group where people are at similar stages of life and want to make connections. That doesn't automatically mean slower music or less challenging figures.
The key difference is between an invitation and an exclusion. The wording particularly suitable for couples aged 50 and over speaks to a group the class is intended for. Participation exclusively for people aged 50 and over, on the other hand, sets a limit. The label 50+ alone leaves this distinction unclear. Photos of older couples don't answer that question either.
Take a couple aged 47 and 55: in an adult beginners' class with people of mixed ages, the age difference doesn't need any special explanation. In a specifically age-restricted 50+ class, however, the younger person may fall outside the concept. The age difference between you isn't the same as a course's age requirement. A couple with only a few years between them may be excluded by a fixed age limit, while a couple with a larger age difference may be welcome in an open class.
