Thanks all for the very helpful replies. We are a UK couple so gratuities not an issue.
Sailing from and back to UK port (Dover in this case) certainly appeals having missed 2 days of a river cruise this summer due to BA flight cancellation. Do I recall correctly that you have the option of free parking at the port rather than the chauffeur?
Long term Viking cruiser considering Saga Midnight Sun cruise in June 23 because the itinerary is just right. How do the two lines compare? They look very similar but am I in for any surprises?
