  • Chloe Blake
“I went on the trip of a lifetime. I made met some amazing people and made some incredible memories. Every single part of the tour was just stellar. The leaders did a great job looking after us all and ensuring we still had the best experience. It was my first time doing a tour along with travelling alone and I would 100% recommend it to everyone. I cant wait to get my next tour booked.”

“This tour was even better than I was expecting! All the places we stayed were awesome. I loved Phi Phi and Koh Phangan. The trip was such a great variety of activities, it had a little bit of everything. Going on the 18 day Thai Trip was the best decision of my life!”
Holiday of a lifetime

  • Ben Scarott
“All the activities in the trip were amazing! There was always something to do and the group leaders were very knowledgeable. The meals and getting around was all great too. Our group leader made it a holiday remember. For me and all the other members of the group. He was always up for a laugh and got all the group singing and dancing. He was great to be around. He became a good friend too, during this trip, everyday is my best day became my quite. It was a holiday of a lifetime and I would recommend this tour operator to everyone!”
