So as to not arrive with “jet lag”

 So as to not arrive back in London trashed with “jet lag” from the overnight bus, we are taking a day bus.  If you book months ahead, the Eurostar train through the chunnel is not too expensive.  But it is vastly more expensive for last minute travelers like us than going by bus.  It would be over 200 Euro each on the Eurostar.  On the Euroline bus, we are both traveling for under 100 Euro.  This price includes a “concession” or discount for our being old.
