The one thing I don't like about Princess turkey dinners is that they don't let you order a leg or thigh. It'd just the standard dinner that's available.
Only occasionally do they have a carved turkey in the Horizon where you can specify what piece you want.
I think next time they prepare turkeys I'll check with the head waiter early in the day to request a special plate be put aside with a whole leg. Other than saving a leg it doesn't require much special preparation.
