Please don't fret about amenities like ice, food an beer, camping equipment, or anything else you might hanker for. This is the USA dammit. Unlike Le Mans (or Silverstone, Donny Park, Spa, etc) you are treated more like a customer than an inconvenience, so there's no need for anyone to get their knickers in a twist over ice. There is plenty of ice, I promise you. It's Florida for fucks sake.
