Since the discount is percentage based recovering your cost for the card is completely dependent on the size of your group and how much table service dining you plan and how much alcohol you drink.
We are a family of 3 and for us, we used it all we could for a week without having to go TOO FAR out of our way to find a place that accepted it and we were still about $15 short of recovering our $65 investment. Trip # 2 was a short 4 nighter and we finally broke even (I think we used it twice). FINALLY, our 3rd trip with it was another quickie (3 nights) and we finally were in the clear by using it at Jiko and Boma and at a CS place in AK. We drank all we could and we ate all we could afford...but for a smaller family eating "average" meals (mix of CS and TS) it takes a lot of planning to get the $65 back.
I think it's GREAT if you're a larger family or have older kids that eat more than mac & cheese... I am glad we tried it - will probably get it again IF we're going with more than just the 3 of us so we can get a good discount on some TS dining for a larger group...otherwise it's like work to get your money back...
