First, the communication from the tour operator was not timely or proactive, and was totally misleading as to where we would meet the tour guide and driver. This is a Shore Excursion - when you get off the ship, all of the buses, independent tour operators and taxis are right there - but no one had a sign with our name. Since I had a number, I had to phone the operator at 1.79 per minute!, who then sent me a text with the tour guide's phone number, but no explanation. So now I had to call the tour guide, again on my nickel, asking where he was. In very broken English, he was trying to tell me where he was, but I never could understand where he was telling me to go. Finally with some help of an experienced traveler off the ship, I was able to understand that he was outside the security gates, nearly 3/4 of a mile walk from the ship. So we had to walk that distance across lots filled with cargo containers, and had to dodge vehicles loading and unloading containers from trucks. He told us that he was not allowed to meet us at the dock, when in fact the answer is that there is a charge to come in, which the tour guide was unwilling to pay. As for the tour itself, it went pretty well, but we really didn't see that much considering it was a full day one of the things we did was sit in the tour guide's favorite coffee shop for 45 minutes - so he could have us experience Vietnamese coffee!. We learned that some acquaintances on the ship just used a taxi driver to get them into the city and they experienced more than we did. Admittedly, the Cyclo ride was a kick, but at the end, we were guilted by the tour guide into leaving an excessive tip for the drivers. At the end of the tour on the way back to port, we had to drive out of the way through heavy traffic to drop off the tour guide at his favorite coffee shop again. This meant that we lost at least 20-30 minutes of our t our time. This tour was a bust - we feel ripped off and it's highly unlikely that we will use Viator again, despite the fact that on this same trip, we had an outstanding tour in Hong Kong.
