My wife and I recently enjoyed a holiday in Crete and while we were there we thought that we would take a trip to Santorini from Rethymnon. We booked a SEAJETS excursion through Dolphin Tours in Rethymnon for Tuesday 4. August 2009. We received a telephone call from Dolphin Tours on Monday 3.August.2009 to say that the trip had been cancelled! We were given the option of transferring to the excursion which was due to take place on the following Saturday 8.August. 2009 which we were happy to take. We were told to report to the Rethymnon port for the earlier time of 0630 for a 0700 departure. We arrived at the port at the agreed time and waited...and waited... and waited but no SEAJET vessel arrived. We called in to the Dolphin Tours office where we were told that once again the trip had been cancelled. No explanation was given as to why the excursion was cancelled nor indeed why we had not been informed of this. Had we known that SEAJETS was so unreliable we would not have booked an excursion with them. We left Crete shortly after and are extremely disappointed that we were unable to see Santorini.
