Garden grocer is so incredibly efficient - they take one less stress out of Disney park planning when traveling, especially with young ones. Our impetus to use them was to save a little money at the park, if your family wants more than one 'snack' a day your jammed into paying 2.50 for a bottled water. I chose several of the 'Store Brand' items (specifically for cases of water and paper goods) and it proves far more reasonable than others. We highly recommend garden grocer!
Food in coolers kept nice and cold, prompt service, and excellent staff to talk to.
