I have decided to travel from Puno to Cuzco on one of the tour buses with stops at different sights along the way. I've done some search on the forum and everybody seems to be happy (happier) with Cruz del Sur, which is not running the route any more...for the rest of the companies (Inka Express, Wonder Peru, Tourismo), is there any actual difference among their services? I found some comments regarding bad experience with Inka Express, but guess it was mainly a guide issue which could happen to any company. From the websites, all 3 companies offer exactly the same itinerary with minimal price difference...
Any comment will be greatly appreciated.
