DH and I are looking for ideas for our wedding anniversary in June - I've found a great cruise going from Cologne to Basel on the Rhine with Riveria travel at a good price but I'm slightly dubious as to the age of the rest of the travellers? I'm in my 40s and DH is in his 50s so we're not spring chickens ourselves but don't want to be stuck on a floating nursing home for a week. Has anyone done one recently??
