We had the same bad experience twice within 6 months! We booked a tour in Edinburgh,after confirming and receiving the payment they informed us that the trip will be canceled. The same incident happened in Budapest and not only they took the payment and never assigned us a driver, we had to call them on a Greek line (that was the closest destination they have support line) and find out that our trip was canceled under the excuse that they didn't have an available driver. That conversation took place 1h prior to the trip, which is unacceptable since we lost our time. Since they are understaffed and don't have the adequate sources they shouldn't preauthorise credit cards until the driver is assigned. I don't recommend it unless you have time to lose.
