We used Netgrocer last May when our vacation was 10 days. We ordered about 5 days before and had the package delivered the day "before" we arrived so that it would be waiting for us. Obviously, they only carry non-perishables. It saved a lot of money. We ordered bottles of water (.99 instead of $2.50 at the parks), cereal, pop-tarts, peanut butter, bagels, kid's juice boxes, twizzlers, cookies. It was great and we strongly recommend them. Just find out beforehand whether or not your hotel will charge you for package delivery. We stayed at the Contemporary and I emailed them and they replied that there would be no charge. (Save the email). I was indeed charged $25 (above the shipping costs from Netgrocer). I showed the CM at check-out my email and they waived the cost. So make sure you find out before. Hope this helps.
