Traveler's checks are now widely considered outdated and a hassle. You run the risk of wasting time looking for a place that's actually able to cash your checks, and you'll be hit with hefty fees and poor exchange rates when you do. We advise you to rely primarily on plastic for travel money—credit cards for big-ticket items and debit (ATM) cards for cash.
Always pack a few plastic baggies in different sizes. They are great for swiping food for lunch from the buffet breakfast or for saving the seashells your child collected. As a bonus, bring a small, collapsible cooler with a baggie filled with ice from the hotel to keep your lunch cold or to refrigerate something you pick up from the store for later. There and Back Again Travel
“I’m a firm believer that everything you need for a trip — whether it be three days or three weeks — should be able to be packed in a carry-on. This is simple once you master the art of layering your clothes. Choose a color combination for your attire and pack only pieces that match this so that you can mix, match and layer to create different looks (instead of packing completely separate outfits).”
