You just need to be an AP to be eligible, and you only need one card per table (although there might be limitations to the size of your dining party). We have been using this for the last few years instead of getting a dining plan, and it can pay for itself in just one trip! I believe the only blackout dates are on the major holidays; I think Mother's day was listed but we were able to use it. They do add an 18% gratuity to your bill too, so you don't have to calculate the tip, it's already included. We've really gotten our money's worth from it.
