We took our insulated mugs and we were thrilled that we did. But I can honestly say that I did not see more than 15 other people with them all week. On my first morning out I have to say I was a little embarrased to be getting out this 23oz neon green, wal-mart mug. But after the first rain storm and I had sand in my drink I did. My husband, kids and I were stopped by dozens of people saying "what a great idea, can we buy those in the gift shop?" They are definitely worth bringing. And the bartenders had to love them. After you watch them cleaning up glasses on the beach, pool area, etc for hours, you know they have to wish that every person brought them along.
