Getting a house with a bunch of friends for a 3 day vacation in April. Will be 10 adults and 15 kids

I've got to cook dinner one of the nights. Got an entire kitchen and a grill at my disposal. We're doing burgers and hotdogs for the 2 lunches, so I can't go that route...looking to take it up a notch or two from there...but at the same time, this doesn't need to be a 5 course meal. Any ideas on what to cook? Initial brainstorms are the following:
1. Marinated chicken skewers with peppers and pineapple
2. Taco/Nacho bar
3. Grilled Pork Tenderloins with various sauces (grilled veggies as side)
