What people love about Thailand, Cambodia and Vietnam Tours for Young Adults
- Southeast Asia Discovery: Seasides and Street Food
Totally amazing. Well organised, friendly guides, small groups of similar ages, varied activities, visited local people's homes, used local guides, very nice hotels even though it was the basic tour, no problems of any sort. Definitely would use them again
- Cambodia: Ancient Ruins & Boat Rides
Tour Guide Law was excellent. Accommodation was a bit lower than I expected. it was a great experience overall
- Amazing Vietnam & Cambodia & Thailand ends Bangkok (4 Star Hotels)
This trip was amazing and you do a lot in three countries but 16 days is too much with out barely any free days, I would have liked a few more free days to relax and take it easy. otherwise the trip and stays were pretty amazing.
