Key:membership

Many facilities may only be available to those who join a membership scheme. Alternatively, non-members may use the facilities, but may have more restricted rights. Typical examples are:

• Membership Stores: most typically, so called  Warehouse Clubs, such as  Costco,  Sam's Club, which are common in the USA. Some cash and carry stores in Europe also work with membership schemes: e.g.,  Makro.
• Fitness facilities. Often referred to as "gyms" or health clubs in english-speaking countries. Examples include:  David Lloyd Leisure. The tag may be appropriate to separate leisure=fitness_centre facilities which are only available to members.
• Social Clubs. Social clubs which may act as pubs may require membership, although this may be in the form of temporary membership.
• Sports Clubs. Most regular sports clubs are membership organisations, and in general the tag is not needed.

Usage

• yes: membership is possible but not required to make use of the services
• required: membership is required

Similar tags
