I just called WDW Dining about this, since there is nothing on their website about how many credits the CP package takes, just how many a normal meal at each restaurant takes (1 TS credit). All CP pkgs, whether for breakfast, lunch, or dinner, and no matter the restaurant, take two (2) TS credits. Which makes them different from Fantasmic!, whee the meals are the same number of credits with or without the package. (So, Mama Melrose and H&V are 1, and HBD is 2.)
So, basically, for my crew, I have to decide if it's worth using approx. $150 in second TS credits to get a guaranteed seat at CP. The sad thing is, because there's no way we could wait 3-4 hours in a CP line (esp with no guarantee of getting seats), it is debatedly worthwhile.
