No matter what city or town you are in when traveling around Vietnam, there will be a number of tours that you can take, from morning tours to multi-day sleepovers. Some of them are great deals, with lots of value for money, others are complete rip-offs with loads of waiting.
Another hit and miss is the tour guide. A good guide will give you loads of information, and hopefully have a great sense of humor as well. Vietnamese do have a great sense of humor, once you get them to drop their salesman facade. Unfortunately it is so hard to find out what your tour guide is going to be like before you start the trip, a lot of tour operators have never even done the tour before, and they will say anything to get you to buy.

They usually chuck in a stop or two to get you to buy some trinkets, but there is generally no pressure, and they might put on a demonstration on how to make hats or incense sticks.
The extra stops may cost extra as well, each of the tombs on this tour cost 55,000 dong extra, the Garden house was 10,000 dong, there were extra options for lunch (which consisted of rice, tofu, and cabbage), and
