Royal Caribbean Cruise Drink Package Cup Holder

If you've been on a cruise with Royal Caribbean Cruise line and got the drink package you know that they provide a specific refillable tumbler to use at their soda machines. The issue is that you have to carry around the cup constantly and that might not sound too bad but after 4-7 days of carrying it in hand, it gets pretty annoying and you wish there was somewhere to put the cup. This is my attempt at designing a simple and inexpensive tumbler carrier that will fit those specific 20 oz tumblers that is minimal in look and doesn't attract a ton of attention. This one is designed to wear around your waist with a $10 1" belt system that I bought off amazon that made belts for the whole family. I've made this in preparation for a cruise we have coming up so I haven't actually used it for a week or whatever yet but this is what I'm going in with next time.
