Tipping on the Hop off tour bus..

[nanatexas]

Do you tip the driver when you get off the bus? Or is just part of the service of the boat?

It's kind of difficult to tip as you may have several drivers and tour guides over the course of the HOHO route.  The same drivers go from port to port and you'll get to know them so I suppose you could tip one or more at the end of the cruise.

Never done it.  You are on and off the bus so quickly.  I think (hope) the bus drivers share in the daily gratuity.  And the tour guides are local volunteers who know all there is to know about the town.
