Ive done 3 trips with intro and loved them all, but my most recent one with Jabs and Sophie in Vietnam was especially memorable. The trip was very well organised and we covered a lot of sight seeing, activities etc. Jabs and Sophie were always full of energy and happy to help with anything and everything. I would 100% recommend intro tours if you enjoy travelling!

"Awesome time in Vietnam went with my 2 adult children and husbandLucy did a great job of creating a fun experience that was exactly what I was looking for . Only had one hiccup with communication but overall the places we stayed were amazing and fun Asia is a little gritty – it is a more challenging vacation than Europe for sure – so you will need help with transfers and getting around . English is not as expected and a lot of people do not speak it ( Europe English is a second language. Here it is not so) due to communist infrastructure People were super nice tho and Really loved Hanoi / Mekong delta / Hoi An It was very different than any other places you may have gone Highly recommend Lucy and This Tour operator"
