Horror!
It all started small. Instead of a normal bus, a minivan with two seats at the exit (which obviously has no place there), or rather at the exit ... because the person sitting on them has to constantly get up to let others through. But you'll be told, minivan, it's good because it can drive anywhere (remember that) More more ... Not to mention the tour operator's constant advertising of its "beautiful places" and the shops you have to visit.
