My family and I stumbled across Asia Pioneer and we had the wonderful Chloe as our travel agent for our Vietnam/Thailand trip. Everything was organised for us, from the itinerary, to accommodation, tour guides, drivers, flights and activities.
It costed quite a bit, however well worth it if you don’t want to worry about having to organise anything.

I highly recommend!!!
My only feedback would be that the payment system with Asia Pioneer is not straight forward and they invoice and quote in US $ so if you are from other countries tries the conversion rates and credit card fees etc become quite confusing and it ends up costing more than expected.

They request a 30% deposit upfront which is fine, but then you pay another amount a month th before the trip, and then the final amount in cash on the day of arriving in Vietnam.
I recommend you get the cash out in your country before arriving to Vietnam as the ATM’s only allow you to get out a very small amount (3 million vietnamese dong) at a time.

However other than that, highly recommend !!
