Just my two cents ...
If the ONLY reason I was getting a car was to get groceries, I'd skip the car and jump at the idea of a grocery delivery service.
Number one, the service charge will be cheaper than the car rental.
Number two, the process of getting to the car rental, driving to the store, shopping in a strange store (not knowing where things are), bringing back your groceries, disposing of the car ... 3 hours easy. NO WAY I'm wasting 3 hours of my vacation on chores if I have an alternative. The alternative is the grocery delivery. If you order through
www.goodings.com, they deliver to Bell Services, and they'll hold it for you (even keeping the cold stuff cold) until you're ready to receive it ... this means you take ZERO TIME away from your vacation. Garden Grocer can deliver your stuff to Bell Services rather than making you set a time to wait for them, but you have to request it.
We skipped Disney this year and spent a week in 2 Canadian cities. I was SOOO disappointed when I learned that there was no grocery delivery service in the first city. I was looking forward to arriving at my first hotel and getting the groceries from Bell Services and being set. Even though I had my own car, I didn't want to waste the time going to a supermarket.
With Gooding's and Garden Grocer, you are NOT limited only to what's listed on the website. Garden Grocer is a service, and they'll get you what you want. Gooding's is an actual supermarket that also offers delivery, so they will deliver anything they stock on their shelves, with the exception of alcohol.
