“Everything about this trip was incredible. Our trip leader, Zinni, was nothing short of amazing in sorting things out for us or just making the bus rides and adventures in new cities more exciting. The people I met on this trip I will be friends with for years to come and the places I got to see, over the busiest part of the year (Christmas/New Years) was unreal and wouldn't have been anywhere near as good if I had booked it all myself. Our driver, the hotels, the included activities and meals were all fantastic. I couldn't recommend this trip enough.”
