No regrets on the trippl Azzurri. I firmly believe its the best type at QR. The managment has come a long way to improve the corporate culture especially in the training department lately, and it has thus become an overall positive experience. The main concern is the one mentioned above and the hopes run high that it will be solved with the arrival of the new COO.
As for the lifestyle, I would not dare to neither recommend the move or not. The Middle East experience is unique and interesting in its own way. Generally speaking, familly life can be decent in Doha, for singles it is much harder. If you are a positive person, like to interact with very different cultures, and look for new experiences, it might be the right decision. If you lean more toward being conservative, you certainly are taking a gamble. Good luck in your decision.
