• No matter the time of year, you should have some sunscreen with you.
• If you’re going someplace remote, think compass and maps.
• Check the guidebooks for local customs, and follow them—especially about tipping.
• Have a dietary restriction? Make it very clear to the waiter.
• Breathe. Don’t create one of those every-moment-booked itineraries. You need downtime and discover time.
• Have a great time. Literally! Tell yourself this trip will be fantastic, and get into the mindset that all will be good. And it will.
