if you do end up paying for 6 but only using it for 3, you will still have 6 TS credits and 6 CS credits, so on your three days at the parks, you could do signature restaurants at 2 credits per person, and breakfast & lunch 1 CS each day. And then you'd have 6 snack credits to use up in 3 days, too. Would be like having the deluxe. Just a thought.
