I couldn't find any iced coffee anywhere back in Aug 2004. Finally, by the end of the week, I couldn't take it anymore. While at MGM, I went into Starring Rolls and asked, ever so politely, if they would put the same amount of coffee they would put in a small cup into a large cup and provide me with a cup of ice. I sat down, put a very small amount of ice into the coffee. When you do this only that amount of ice waters down the coffee, but it get the temp down. Then I added more ice, my cream and sugar, and viola! I got my fix! Grant it, it wasn't great, but it was better than nothing.
I just realized you'll be at the Dolphin. Purchase a nice cup of the Starbucks coffee they serve there at night. Be sure to get a cover. Keep it covered until morning, then ice it down. I don't like the Nescafe stuff they sell in the Disney resorts, otherwise I'd do that everynight.
