I think a lot depends on your class. I was very involved with our 40th in '09. We had a great venue, buffet dinner with several choices, cash bars, decorations in blue/white/silver. We also had a "memory" wall for those we had lost, and display walls/tables filled with memorabilia....you'd be surprised what people save!! We had cameras on each table, and the music was "recorded" so we could control the volume. We had a great time. Our class had 150 in it, and for the most part, every one got along and liked each other. We truly enjoy getting together. We also hold an after party for those who don't want the night to end, followed by breakfast at a local eatery. No need, or time for games...everyone too busy talking and catching up!!
