We have several of these (way too many actually

) from our first trips starting in 1994. They came with a couple of the drinks at the Gurgling Suitcase. I know The Turtle Crawl was one and maybe The Sultry Seahorse. We have dolphins, turtles, anchors, whales, seagulls, santas, and christmas trees. These all have the inscription "Disney Vacation Club Resort" on them. After a time, they did offer them in the drinks, but they were without the inscription. Not sure when they stopped putting them in the drinks, maybe around 1996 or 1997.
