When traveling during Tet holiday, everything is going to be a lot more expensive and things are going to book up fast. We decided to go to Mui Ne because it was a cheap to get to from Saigon. Make sure to book accommodations and bus transportation a week or two in advance! We messed up and booked our bus back to Saigon the same day we wanted to leave. Not only did we have to leave earlier than we wanted, we also had to pay double the price to get the last seats!
