It depends on the tour.
For guided tours and bike and boat tours, we can often check for availability. Please contact us and let us know the tour and tour date of interest.
For self-guided tours, we can't confirm availability. This is because the tour operator does not have blocks of rooms reserved at hotels for every possible start date. Tours are "on request," which means they must receive a booking request from us and will then check for availability at each hotel along the route.
A final note - if you're organizing a larger party, many operators are willing to hold space for a short period of time to give everyone in your party time to book. Please contact us for further details.
