Hoi An is way smaller than Saigon. My favorite thing that we did was a cooking class. We made our own noodles.
I liked our hotel. Unfortunately, even though we were on the beach, the red flag was up the whole time, so, we had to swim in the pool instead of the ocean. Fortunately, the pool was the clearest I have ever swam in. There were two good restaurants. One was called Mermaid. Its sister was called Morning Glory. They were both really delicious.
We also did a bike ride around the rice fields and to the weekend market.
