Does anyone have any tips on labeling or other ways to tell whose reusable drink cups are whose? We are cruising on Adventure in 2 weeks with 4 kids and all 6 of us have drink packages. I don't know what the cups look like so I cannot tell if I should bring a colored band for them or do some vinyl decals. I know my kids will fight over who has which cup, even though they are exactly the same! ?
Thanks!
