Hotel pick up was on-time and tour guide spoke good English. Transport was excellent in terms of comfort levels and number of tourists. We had 6 in our group which made the tour easier especially around Cu Chi Tunnels as with a small group, we are able to see and interact with the sights unlike with a big tour group as it may be difficult. Mekong Delta was pleasant too and tour guide did not push for us to purchase things or tip the locals if we did not want to.
Only small downside is perhaps giving us more time to experience Cu Chi but given the number of people when we visited, this was understandable.
