This tour operates by double-decker bus. The cancellation deadline is 3 days prior to the port call. Any cancellations made after this time will be non-refundable. Due to height restrictions within the port, the crystal bus is unable to pickup guests from the port. Therefore, guests will be transferred by coach to the Crystal Bus Depot. There is minimal walking on this tour but there are 10 steps to negotiate to reach the upper deck. One soft drink or mineral water is included.
