You can book your Vietnam tour at any time and generally the earlier you book, the better. Booking early (3 months or more recommended, 6 months in advance for peak season dates) is especially important for travelers visiting during the height of the high season to ensure that first choice hotels are still available. Further, we usually recommend that you wait to book your international flights until after your tour is confirmed. The sooner that we arrange your tour, the sooner that you can take advantage of flight deals as they become available. We are often able to accommodate last minute travelers as well (some even departing in less than one week!!), so give us a call and we will do our best! For last minute bookings, it helps to be flexible and organized. Your first choice hotel may not be available for your selected dates, but your trip planner can recommend some other similar options that would be equally interesting!
