I am curious how the new dining plan works as far as the gratuity for servers. It seems to me that if the dining plan "dinner allowance" is a flat rate then the tip would be a flat rate too. I think I heard that the gratuity is included?? How is that calculated? I would venture a guess that for buffet servers it's a better deal than for regular table service places, since at a buffet I tend to tip a little lower (12 - 15%) seeing as how I do most of the work myself. In a full-service restaurant I rarely tip less than 20% unless the service is poor - which has never happened at a WDW restaurant (except AK Rainforest) for me.
