I’ve been river cruising since 2011 and I know that others on these boards discovered it many years before we did, I really feel for those who’s first try has been this year, somehow or other we’ve missed low/high water levels etc. We’ve had indifferent tour guides but never a bad one mostly good to absolutely excellent. I sympathise with your dislike of the lack of self service but it’s a throwback/ ruling from covid which for river cruise vessels may still be in place. Yes this year we had a couple make a b-line for us with the dreaded cough and snivelling, unluckily I have a heart condition so it didn’t turn out well for me but they insisted that they had tested themselves and were free of Covid - yes but not the sniffles and snuffles. Bonus I could do the cruise for a third time after a few others. We’ve made acquaintances from around the world wonderful people we would never have met otherwise. Afternoon sitting up front with a glass delivered by a very pleasant young person to a group of, okay yes getting on or nearly getting on members of the Commonwealth with a few honorary members from below the border nothing better. I’d say give it another try and enjoy.
