Honestly, your biggest concern for travel is how well you are going to be able to handle sitting down on whatever seat you get (car seat, plane seat, train seat, etc) for whatever period of time you are traveling. You would be advised to make sure you travel with your donut cushion.
It also hasn't been six happy weeks after surgery, this has been no vacation (holiday for you UK folks) healing up from such a major surgery. The first two weeks were very grueling, but once I got home things got a lot better quicker.
