The answer depends on the type of food platter you are wanting for your event. In general it's always better to order at least 2-3 weeks in advance of your event to ensure that the Costco staff have adequate time to prepare in case of multiple events foods being picked up on the same day. That being said, I agree with Rick H that to get specific information regarding the specific food platter you're wanting for your special occasion, it's best to go in person and speak with the staff personally to arrange pickup date/or (if available) delivery options to your event. Hopefully that will ensure that mistakes aren't made and everyone is happy with the results. Hope this helps and have a great event!
Unfortunately the question doesn't make any sense so you really can't answer that you should probably go in and talk to them.
