Forget the gas station and the taxi to buy groceries. This is the only way to get your groceries if you don't have your own car. The food is delivered on time and the prices are better than your local resort shops. Empty out a suitcase to carry your groceries from the resort delivery room to your room. The food planning is the hardest part.
I had an extremely wonderful experience with garden grocer and have already told friends and family about the site for all future travel needs!
Even though prices are higher than shopping myself, it was convenient because I did not have a car while on vacation.
