The key question is if you can get ginger beer on Aruba. I don't know because I don't use it. You could pack your copper mug and the recipe and I bet any bartender would be happy to make it for you on Aruba. They should have all the other ingredients. You just need to find out if you can get ginger beer there or bring some with you. Bartenders like to make their customers happy because they live on tips. You can buy the copper mugs if you don't have one.
