I ordered bottled water, granola bars, and a few snacks for our recent trip to DL. We stayed at the Grand Californian. When we checked in, I asked about my delivery and they brought it to us. The delivery fee for one box is $5.99 - my box was not full and had 18 waters, 2 boxes of granola bars, and a few other snacks. The items probably cost a bit more than you would find at your local grocery store, but not significantly higher. This was a significant savings over buying bottled water in the parks and we ate the granola bars for breakfast. We each took a water with us in the morning as well as snacks, and since we were so close to the hotel, would pick up a second later in the day. We did fill the bottles at the water fountain on occasion, but did not really care for the taste of that water. If it were just two people, it might not be worth it, but any more, I think it is. At DW last year, we used Garden Grocer and liked it, but that option isn't available in California. I believe Von's delivers and you can get refrigerated items, but I think you have to be there to accept the delivery - they also occasionally offer free delivery is you sign up on their website. There was not a problem taking these items into the parks either.
