Sport Club = Same as above with basketball, raquetball
Supersport Club = Same as above with wet area (pool, Spa, Steamroom etc.) tanning, massage areas, aerobic, yoga, blah blah blah a bunch of other trendy stuff.
The memberships vary, for the regular club its like 30 a month step up to the sport club is like 45 or go to all three for 75. The catch is that you can only go to one specific club and no other with the 30 and 45 memberships. With the SS club membership you can go to any club any where in the world....I have the SS Club membership and find it very convienent to not be limited to one club.
