My opinion on the reason for touring is that the cost may be roughly the same, a cheap hotel against a shag pad, but if you don't have the ties, a husband, boyfriend or children then the attraction of being a "new girl" in an area would bring in more work than if stuck in the same place, even perhaps if the hotel was costing a little more.
In my experience services are as different with tourers as they are with stay at home SPs, it's not possible to generalise.
