I did bottles for mine - around 150 total, but I brewed and bottled it over the course of several months as it was ready. We didn't have time to properly label them (a friend made sheets of pretty but unworkable labels that had to be hand-punched), so we told everybody what the kinds were and half the fun was trying to choose the kind you wanted based on color or comparing this one to the last one you had.
We just went to Home Depot and bought two big steel tubs and filled them with ice, beer, pop, and water. One of my jerkface friends loudly announced there was "no more beer" after an hour because all the bottles had gone into the tubs - I think there were still 100 beers on ice, lol.
I didn't have kegs at the time, so bottles were my only option. They worked out great though, even though all the bottling (and later the cleanup) was kind of a pain in the ass. It was nice to have them all stacked and ready when the big day arrived so that there was no setup or fiddling. Just bottles into the ice, and a few bottle openers and a stack of cups nearby, and everybody knew what to do from there.
