[Tagging] Tagging a sports club with a closed way

[Dave F.]

This is a general query that could apply to many organisations, but as 
an example I'm going to use a tennis club to illustrate.

This club has on it's site a car park, clubhouse, a garden & a few 
tennis pitches. These I can tag individually & render successfully.

However what can be used as a closed way to encompass the whole site? 
Previously it was leisure=pitch but that should be used just for the 
tennis courts.

Sports_centre appears to be used for multiple sports.

Any suggestions?

Cheers
