It depends on the tour, but in at least one case when reviewing the bills afterward we noted that I had spent less on tour than I would of at home in large part due to not putting gas in my car. That said some tours I spend more and some less, but it certainly can be cheap if you want it to be and make choices that allow that to happen. I guess if you have lost income that makes a big difference, but if retired or on paid leave it can be pretty cheap.
