Guess it depends on what the activities are. We'll probably need to cook for breakfast and for lunches when we're at the Castle....plan on something that's quick or easy in the evenings if we're going to be out evenings or late afternoons, and all afternoon cooking if we're just gonna hang around the Castle at night.
On Saturday, we'll make breakfast and then watch the movies, with a break for lunch that can be sandwiches again or order some pizza or something. Finish watching FOTR and TTT, go to the theatre, watch ROTK and maybe go out together to grab an affordable bite to eat or else we could pick up some fried chicken, etc.
Sunday morning, same drill - breakfast and then lunch could be leftovers or I'll buy some hot dogs and burgers for a grilled meal! Dinner is a la carte since some folks, like me, will be leaving that night anyway. :-(
