This tour felt like a crash course in Southeast Asia, but in a good way. I wasn’t sure how much ground we could realistically cover in just over a week but this trip proved you don’t need a month to experience something meaningful. Everything was well-organized. What stood out most to me was how different Vietnam and Cambodia felt, even though they’re neighbors. Hanoi was buzzing with life..scooters zipping by, food stalls everywhere, and this mix of modern and old that was fascinating to watch. Our guide helped us navigate the chaos in a way that made it feel approachable rather than overwhelming. Then, just when things felt fast-paced we got a breather on the Ha Long Bay cruise. Being out on the water was peaceful, the views were unreal. In Cambodia, Angkor Wat was the big draw, and yes, it was absolutely worth it. But what I didn’t expect was how much I enjoyed the in-between moments. And while there’s always a lot of walking on these kinds of trips, the pace felt doable, even for those of us who aren’t exactly as young as me (53 :p) Would I do it again? Definitely. The trip left me feeling like I got a true taste of two cultures.

What made this trip really special was how different each day felt. One day we were walking through old temples, the next we were sailing on a quiet bay. Vietnam was full of surprises. The people were friendly, the food was amazing, and every place had something new to offer. Ha Long Bay was a real highlight. The boat ride through those tall limestone rocks felt peaceful and looked like something from a movie. Even the meals on the boat were great! I also liked how we didn’t just rush from place to place. There was time to look around, take pictures, and enjoy it all. Hoi An was beautiful with all the lanterns, and Hue had some really interesting history. Our guide explained everything in a simple and fun way, which made it more enjoyable. Then we went to Singapore, and it felt like getting into the future. It was super clean and modern, but still full of culture. The Gardens by the Bay were stunning, especially at night. Everything on this tour ran butter smooth, the flights, the hotels, the transport. It was easy to relax and enjoy. Already thinking of booking a Korea tour. Really impressed by how they manage things!

Hello, following our recent trip in Japan. I would like to pass on the following feedback. Firstly, I would like to congratulate all of your staff for their professional, helpful, informative commentaries for our daily activities. Although there were relatively small groups of English speaking guests on the tour we were always included and I was most impressed with the overall set up. This was our first group/tour style holiday and I would definitely look at booking other trips in the future based on this experience. The only negative was one guide whos comprehension of English was only just adequate, as when presented with any questions he was unable to give succinct answers, and often just glossed over explanations which fell short overall. Conversely another guide David Muñoz was absolutely brilliant, his English speaking and comprehension was excellent, he managed his section of the tour with ease, engaging all guests equally, the knowledge he was able to pass on far surpassed the other guides and for this reason I am writing this message with the hope he will be acknowledged for an outstanding job. He was detailed with sharing knowledge and made the whole group comfortable with one another. All meals and hotels were fantastic, until we travelled with Maria, I and many others in the group felt that the standard of meals provided with the exception of the Roykan and Monastery at Mount Koya were sub standard in comparison to that which wed been provided prior. Excellent experience overall, manager/supervisor should review restaurant locations offering for final part of trip, acknowledge outstanding staff performance and address staff whose comprehension of English was not of a great standard. The variation of locations and sights was fabulous. Very well thought out itinerary, highly reccomend.
