I am visiting in a couple of weeks, and my friend who just came back (she stayed at the Contemporary) gave me some tips about ordering from Garden Grocer (we are both on the dining plan):
Order bottled water to save the snack credits for actual snacks;
Order heavier toiletry items to save on baggage fees (like hair care products and other bottled items);
Order snacks and breakfast items for the room to use meal credits for lunch and dinner;
Call your hotel in advance and ask how they handle the orders when they arrive - some (not all?) keep cold foods cold until you are ready to pick the order up from the front desk. Garden Grocer allows you to pick a date and time for delivery. Also, my understanding, is that you can request a refrigerator, but others here likely have more information on that.
I hope this is helpful. I have not used Garden Grocer in the past, but am doing so this time because my friend spoke very highly of them.
On a related note, if you have to order from Diapers.com (seems like you don't!), they have a 1-2 day delivery policy. My friend, however, discovered this does not hold true on the weekends. So, if are arriving on a weekend, be sure to call diapers.com and arrange a specific delivery date.
Have a great trip!
