Tim Kroeger
Luxury Wellness Travel & Longevity Editor · Creator of the Restorative Index
I’m a Bangkok-based luxury wellness travel and longevity editor, and founder of Universal Traveller. I evaluate luxury hotels through the details that shape a stay: sleep, calm, food, spa experiences, movement and service.
My central question: Did you leave feeling better than when you arrived?
My Story
Why I Changed How I Evaluate Luxury
I founded Universal Traveller in 2011 and spent years moving between countries, time zones and hotels. I loved the freedom. Eventually, the constant motion and shallow sleep caught up with me.
Burnout changed what I noticed. A beautiful suite meant less if light came through the curtains all night. A spectacular spa could not make up for a room where I struggled to sleep. I started paying closer attention to the practical details that helped me feel comfortable, rested and ready for the day.
That became the foundation of the Restorative Index. I wanted a consistent way to explain why a stay worked, where it fell short and who it would suit.
My background includes a B.A. in International Tourism Management from NHL Stenden University of Applied Sciences, studies in the Netherlands, Bali and Bangkok, and an internship with CRS Tours in Costa Rica. Working as a Lufthansa flight attendant also gave me a close view of service and the demands of frequent travel.
Today, I write for travelers who care about their health and still enjoy a great dinner, adventure and the pleasure of being somewhere new. Travel that restores you.

The Restorative Index
The Restorative Index is my proprietary 100-point editorial framework for evaluating luxury wellness hotels across six weighted pillars. Sleep Architecture carries the greatest weight: 30 points.
It combines observations from the stay with editorial judgment about the room, surroundings, food, spa, movement facilities and service. Scores explain the experience and its trade-offs; they are not a clinical assessment or a guarantee of another guest’s results.
For an example, explore Namia River Retreat in Hoi An, Vietnam, scored 95/100, and the pillar-by-pillar reasoning behind the review.

How Reviews and Partnerships Work
I founded this publication and set its editorial direction. Alongside my own work, contributors bring their perspectives to hotel, spa and longevity coverage. Article bylines identify the author.
- First-hand context: reviews explain what was experienced and the observations behind the verdict.
- Transparent relationships: hosted stays and paid partnerships are disclosed so readers can assess the context.
- Independent conclusions: partnership fees fund the agreed work. They do not buy a positive review or a particular Restorative Index score.
- Useful criticism: weaknesses and trade-offs matter, including who a property may not suit.
- Factual corrections: properties and readers can flag inaccuracies. Editorial opinions and scores are not negotiated as commercial deliverables.

Hotel reviews examine the whole stay. Spa reviews focus on treatments and facilities. Behind the Stay shares first-person stories from the people shaping the properties.

Training, Travel and My Longevity Journey
I combine long-distance bikepacking and endurance events with luxury hotel stays, paying close attention to the food, sleep environment and recovery facilities that matter after a demanding day. Training for HYROX also shapes what I look for in a hotel gym. I want a stay to support both an active life and the pleasure of traveling.
As Founding Ambassador for Healthi Life Longevity House in Bangkok, I document selected experiences and results from my own physician-led longevity program. That relationship is part of the context of my coverage.
Personal testing informs the questions I ask. It does not establish that a hotel or treatment caused a change in my health, and my experience is not a prediction of someone else’s outcome.
