What people love about 3-week Thailand and Vietnam tours
- Southeast Asia 21-Day Highlights Tour
My husband and I completed this trip 2 weeks ago. I have to say this is a well organised tour, we had a great time. All the guides and drivers were great, very professional and friendly. A few tips for future travellers, cash is best to avoid bank fees etc. We were safe the entire time, no issues whatsoever. Vietjet airline seems to shake down foreigners for extra weight by weighing your carry on and combining with the weight of your backpack. Travel as light as possible. Hotel de Bangkok is poor in my opinion, ask for an upgrade and pay the difference. Hoi An Express is a very efficient and prompt tour company, they respond by email and addresses anything concerns you may have. We also booked additional tours with them during our stay.
