We brought the cooler to beach at Divi when we were staying at Divi. We were not "walk-ins" I would not do it at other beaches with restaurants---especially not at Mullet when there's Rosie's delicious ribs.

On another note I personally wouldn't order one dish to split in an upscale restaurant. If it too much to eat then take leftovers back to the unit where you're staying. We each have that "one thing" whatever it may be, that we find rude.
