Cooking for 15 on vacation

We just returned from a week in Hilton Head with my in-laws, two brother-in-laws, two sister-in-laws and lots of cousins. We all had separate sleeping quarters, but ate dinner together every night. Our condo was the dinner condo -- so I usually bought and sort of prepared the main course, and the S-I-L's brought the sides. I think it went pretty well (thus, my need to record it here)

Night One -- Lasagna, Bread and Salad (I brought spaghetti and a jar of sauce by Allison brought frozen lasagnas so we used those)
Two -- Hamburgers and Hot Dogs, deviled eggs, baked beans, fruit salad
Three -- Fajitas (I brought the marinade from home, we threw in flank steak and chicken), black beans, refried beans
Four -- Out to eat
Five -- Pizza ordered in
Six -- Fish and Shrimp (wish I had a good sesame tuna steak recipe), Rice Pilaf, grilled veggies, pasta salad
Seven -- LEFT OVERS (more hamburgers, hot dogs, etc.)
