Sure. We thought we could have up to 200 so we planned for that amount. We got the Green Giant Prime Size Bakers since they are supposed to be fairly uniformly sized. There are around a dozen potatoes per 5 pounds so we bought 85 pounds. We probably served 120 potatoes at most though. I washed them, poked them with a fork a couple of times and put them on large cookie sheets. No foil. It took maybe 1.25 hours at 425º or slightly longer with the ovens full. When baked, we transferred them to three roasters on low to keep warm. We had two ovens and I had the first ones in the oven 2.5 hours before the party started. My mom ended up being the one to keep track of when each cookie sheet-full went in but I think the majority were done before the party started.
We had one roaster with tongs at the counter and just moved more into that one as needed. Had a few steak knives right there for people to cut open their potato. Then we had a tub of margarine, bowls of sour cream, diced ham, bacon pieces, crushed Fritos, and shredded cheese; crockpots of broccoli, cheese sauce, and chili. I estimate we used about half a large tub of margarine (28 oz?), 5 pounds of sour cream, 2 pounds of diced ham, 1.5 pounds of shredded cheese, 1.25 large cans of cheese sauce from Sam's, 3 pounds of broccoli, a large crockpot of chili. I don't remember the size of the bacon crumbles we got from Sam's but we used a little more than half. We kept a spare crockpot of cheese sauce heating so that when the first ran out we didn't have to try to heat it up quick from room temp. The broccoli packages could be steamed in the microwave before adding to the crockpot.
It was really pretty easy and self-serve once the potatoes were baked, just kept an eye on toppings that needed refilled.
