We, 3 adults, just completed the red blue and green line for Europe which was 21 days. Excellent guides in Lex and Geno who made the journey informative and were very attentive to our needs. Both guides spoke multiple languages on our tour and as we had booked the English guided tour we had no issues with this. The drivers had to drive the bus through some terrible weather and traffic conditions and we always felt safe in their hands. It was a fast tour through multiple countries which gives the traveler a quick view which can help people decide which places they would like to explore at a slower pace at a later time. A warning to pending travelers to take into account the lack of laundry facilities in the hotels. We traveled 21 days and only had one town with a pay laundry. So pack allowing for this factor. Most toilets on the main roads you will have to pay to use but the guides will warn you before every toilet stop which is roughly every 2 hours. Some places their is a lot of walking to see the attractions. They give ample free time for self exploring at the required sightseeing stops. All in all we had a lot of fun. This is our second tour with this company and we will definitely book another tour with them.
