In general, we always try to keep in touch with our customers by exchanging full contact details: e-mail address, phone numbers, accommodation address and other contacts. If you are running late or are unable to show up, it would be appreciated if you informed us that you are unable to reach the meeting point on time, as soon as possible.
This way it just might still be possible for you to join the group and not miss your tour. Unfortunately, if you do not arrive to tour meeting point in reasonable time, you will lose your payment (the same as missing you flight, etc.)
