They'll provide PS for one guest, but there were people at mine that brought their parents, too. You just have to let them know on the invite sheet who you are bringing. Check out the wing ceremony videos that Johnny does for each of them to get a feel for the dress code. (The spouses watch the videos for what to wear) Cocktail attire (jacket, no tie-some do anyway). One welcome speech by whichever big wig they send. Open beer & wine bar. Food at mine: salads, sushi, meat/fancy cheese platters, ravioli, and beef wellington. 2-2.5 hours in length. They provide a shuttle to the terminal at 8pm if you want to catch a late flight home. Party wraps up at 830.
