I am a very demanding reviewer, and would have preferred there to be a "Very Good" category between "Good" and "Excellent", because I do not tend to rate almost anything as "Excellent". The changes I would suggest are (1 - as discussed with the group and Astrid) fly in to overnight, then start the tour early next morning ; (2) spend more time in Historic Valencia and if it is necessary to keep to the same tour duration, rather than spending less time in City of Arts and Sciences. It is worth stating that Astrid was an "Excellent" leader in all aspects.
