Pros
Where to begin: riding your bike in amazing places, staying in luxury hotels, eating fantastic meals, meeting interesting and exciting people. Very much a "rockstar" lifestyle, but you work very hard for it. Tips can be really substantial (which is good, because the daily wage is horrible).
Cons
President/CEO: Tania Burke (Worgull) does a very poor job of looking out for the needs of the guides. She is an incredibly smart and capable woman, however she is a classic micro-manager. She also believes that she is the "expert" in every aspect of the company, which is incredibly arrogant and foolish, in my opinion. Guides are paid a very low wage - $75 per day, regardless of the amount of hours you put in (and it is very typical to have 12-16 hour days). Guides are also on their own for all food and phone expenses while they are between trips, which can add up, especially if you are stationed in Europe.
