Food for Moresca Ball

What is the earliest we can come and drop off food? Want to bring cooked bits and uncooked bits, combine and cook in crock pot for at least 2 hrs before serving, is this feasable?

You will want to, and can get there around 3:45pm-4pm and set it up.  Feasting will mostly likely not begin until 6pm.

1 large tray of Meatloaf served in brown gravy.
1 large tray of spear potatoes, carrots, and onions
(These two items will be on serving racks, and be heated by chaffers. Extra chaffers will be brought if anyone needs them)
2 Cherry Pies
1 Blueberry Crumblecake

We have a deal... and I did get the name wrong... it's potatoes au gratin

So 3 large dishes of this sound good?

This will be my first Moresca Ball and a concern occurred to me. I was told that the food is done buffet line style. Are there different areas for vegetarian and non vegetarian food and/or is there some sort of opportunity for vegetarians/people with restricted eating habits to take from the food they can eat before the general population descends on everything?
I almost never speak of special consideration for those of us with pickier pallets but I'm sure I'm not the only one who saddens at the thought of getting to the spread only to find my options being 4 pieces of cheese, some bread and a mushroom.

Considering the great prevalence of crockpots and hotplates that I imagine will be in attendance, would you like extra power strips?
