Don’t forget that your DJ’s need to eat and drink too during your party. Depending on the times, (dinner etc.) your poor DJ may be hungry and he may be suffering just watching everyone else eat. Keep your DJ happy and I’m sure he will do a great job for you.
Your photographer, event planner, all may be hungry or thirsty so make sure they all are at least offered something. We specifically ask ahead of time whether to bring our own food or drinks to the party. Yes, Cactus Dave will maybe drink a beer or glass of wine if offered, but never drinks more than that besides soft drinks or water. Kimi doesn’t drink any liquor at all, but we both like something to “wet our whistle” during the party.
