My neighbors recently went on the Disney Cruise and they had these clear plastic tall drink cups (like the curvy kind you'd get a frozen daquiri in) that had a nice, simple cruise line logo on it. You could get them for $2.00 extra when you ordered the drink and you get to keep the glass. They are really nice quality. - Perfectly suitable to have around as "outdoor-don't want to have actual glass out by the pool" ware. They only brought home 3 and are regretting not getting more to have as a set.
They also recently did us some favors and I'd love to hunt down some more for them.
Currently, Ebay has nothing listed, but I'll keep checking there.
Does anyone have any suggestions on how I might be able to get more?
