@Cyn Great insight. We would class ourselves as experienced sitters and although we have always budgeted for these costs, recently we have been having to factor in any rising costs in areas such as flights, car rentals, gas, and hotels on route or before/after a sit etc.
This might not be the case for other sitters, but it is something we are accounting for more at the moment. This has been discussed before in a couple of threads and may be relevant here as one of the reasons? :
