A number of years ago, I was in Delhi and I went out to dinner, and immediately started to feel that I was getting food poisoning, which was the first time for me in India. So a friend of mine gave me a jar of probiotics; I popped two or three pills, and the queasy feeling was instantly cured. It was the craziest thing. Ever since then, I take them daily whenever I’m traveling anyplace—I carry Pro-15. I also take Pepto-Bismol pills. The probiotics build up healthy bacteria in your gut and the Pepto-Bismol acts as a prophylactic that coats your digestive track like a protective sleeve and can help filter out organisms in contaminated water or food.

Sometimes it’s smarter not to stay in a five-star hotel.

In some [very popular] cities, you’re better off taking an amazing suite in a four-star hotel instead of the lowest-category room in a five-star. In Rome, for example, you can get something really amazing at the Portrait Suites, or in Barcelona, the Hotel Arts vs. the Majestic Hotel.

How to manage your family during vacation—and how to make the most of it afterward.

If you’re on a multigenerational family trip, announce there are three roles: instructor, documenter, and note taker. Every day, someone has to document everything—they’re the cameraperson. Someone else is taking notes, and someone else is in the position of trip leader, so they have to brush up and give a few minutes’ talk on what you’re seeing today. Every day, rotate those roles, and then at the end of the trip, you have a wonderful record. You can also assign one family member the role of editor, who will compile a book of everyone’s photographs and print it for everyone.

How to get a billionaire to subsidize your vacation.

Many of the most incredible hotel properties in the world today are owned by successful business leaders who fell in love with a place and decided to spend time there but also to share it with paying guests—there’s Dietrich Mateschitz, the founder of Red Bull who turned Malcolm Forbes’s private island in Fiji into the sustainable luxury resort Laucala, or Paul Tudor Jones, who leases a 350,000-acre concession in the northern Serengeti in Tanzania and has lodges like Singita Sasakwa and Sabora. They’ve not built it to monetize it, or as a profit center—they’re just very successful people who fell in love with a place and bought it for their own personal pleasure, investing enormous amounts of money to extremely high standards [for themselves]. As soon as you’re there, you recognize it: You’re paying $3,000 per night, perhaps, to be at one of Paul Tudor Jones’s places, but the value of the food, the activities, the comfort? You think, ‘He’s subsidizing me.’ On Laucala, it’s maybe $4,000 per night for two people, all-inclusive, but you literally can be on that island, with the whole place to yourself, and have 400 staff taking care of you.

How to never lose service for just 10 bucks per day.

A friend gave me a Skyroam, the mobile hotspot, a few years ago. You pay $10 per day and it doesn’t matter how much data you use in those 24 hours, whether your kids download three movies or use Instagram, which takes up so much data. Even in a lot of lounges at airports, I use it, as so many people will be on the lounge Wi-Fi it’s too slow, and in a hotel, when there’s a usage charge per device, I can use Skyroam instead—I’ve got five people on the same connection, and I’m not paying the Wi-Fi fee either. The only way you get into trouble with it is if you don’t check the coverage before you go—it doesn’t work in every country, but it’s never failed me. There’s a long list on the website, and it works beautifully in Mexico and Italy and Japan.
