Some observations, but no answer.
It is a RHD tractor so that gives us a fairly limited range of countries.
My best guess so far is that it is a bus delivering passengers to a cruise ship or some such.
Note the "waves" motif on the tractor and trailer. As well, having been on a few cruises, the venue could be the covered hall where you get off the bus, your baggage gets collected and you eventually get on the ship.
Of course, I often come up with very crazy ideas but at least some of the observations may be of some help.
