International travel requires more advanced planning to ensure you have the right travel visas, up-to-date vaccines or immunizations, and a valid passport.
When you’re traveling with friends, there are things you can share, like a hairdryer or hair straightener, maps, travel adaptors, and over-the-counter medication.
The longer your trip, the more items you'll need. Remember, the more days you're away from home, the more variance there could be in the weather.
When you’re staying with friends or family or an equipped Airbnb, you can access a washing machine and dryer. Being able to do laundry means you can pack less.
