There wasn't much to see inside the Cathedral but it was cool and a nice place to sit! We did buy an ice cream cone and then several of our group just sat on the steps and waited for the bus to arrive to take us back to the ship. Speak no evil, hear no evil, see no evil.
I do not think Valencia had anything outstanding to see. This particular tour was ok but nothing special. Upon our return to the ship many of us complained at the service desk. A six star cruise ship should not hire a one star excursion with an incompetent guide. So many complained that even though Crystal Cruises had no responsibility in the matter they rebated 25% of the excursion cost. And I hope that particular tour guide is not retained by them again.
