I have taken a machine with me and plan to do it again! My husband is a golfer...and I am not much of a shopper. I am happy and occupied while he is happy and occupied. I have gotten better at packing what I need. I have a bucket with a pocket organizer (like you can find for tools..but I made mine) I keep it stocked with what I need when I go to class. I also just added a Martelli mat to my collection. It was pricey (!) but it fits in my large suitcase and can be left in a hot car (not forever...but at least while I eat a meal). I try to kit up a project or bring my latest leader/ender project-or both!
Have a safe trip!
