I make ice coffee and carry it in a metal contiga travel mug (get the one with the screw-on top, so no leaking), and I find that there is very little ice melt even hours later.

You might be able to get by for a few hours using metal coffee cups, especially if you carry them in a lunchbox cooler with a few ice packs.
