The coupons offered until this past December 31st did not come with the Convention-attendee restriction. Thus, lots of locals were printing the coupons and redeeming them for free Party Passes. That was not the intent of the coupons so now they carry that restriction. So unless you're attending a group meeting or convention, you really can't use the coupon for the free passes.
The price of a Party Pass is $11.99 + tax for all-club access. I would point out that for $21.00 including tax and including gratuity, you can get a Meal + Party deal that gets you the all-club pass plus a meal in most of the CityWalk restaurants. It's not the full menu but a good selection.
