On a circular A->B->C->D->E->F->A->B->C... I can get on at any point and go to any other. Ticketing restrictions may mean I cannot go around past the same point twice. Ticketing restrictions may mean if there's a reverse of the route then I can't go A->B->C->D->E->F but must take the reverse route F->A. On sight-seeing tours which are round trips, it may not be permissible to get on or off at any point other than A, in fact the bus may not even stop at any POI. On more general tourist round trips, it may be possible to get off some POIs but you must return (otherwise they hang around thinking you've gotten lost) and it may not be permissible to board at any point other than A. The round trip may be linear rather than circular (they usually are circular so that you get to see more POIs, but in the case of an "excursion" the intent is to get from A to B, spend time at B, then return. Different from an ordinary route because they get upset if you don't return to the bus at the allotted time -- Paul
