“They canseled the trip short time before travelling - so there was no trip! No effort to sort the situarion either! Do not recommand you to plan your vacation with this tour, as it appares to us as unprofessional! Also, we then found out the price paied was only for the drive - which can be bought for 1/3 if you go by buss. Going by buss is safe - and will not be cancelled!”
