La verdad no repare en el detalle del tiempo , cuanto duraba si no se usaba en el día

buona sera,la cosa migliore èandare sul sito la fabbrica del duomo e possono organizzare quello di cui lei ha bisogno

I would call the company and ask them.

No terrazze e area archeologica sono senza guida.. solo le terrazze ci vanno un ora se nn ha l ascensore nel biglietto... e quasi 40 minuti l area archeolohica

Non so, mai fatta con la guida, buona giornata.

Si

Anyone can get into the Cathedral. Discounted rates or concession rates are available for the elderly or retired for EC members. There are agents at the ticket office that will assist you through all the way. The roof on the other hand will be a challenge pending on the individual -you can get the elevator up BUT there are steps everywhere from column to column. Not wheel chair friendly for what I remember. Listen dear, the best way is to look up their web, call the volunteers they have working every day - explain your cause and get an answer, everyone speaks English and are super nice. I am sure that you will be very well looked after dear. May the Lord guide your path and have fun where ever you go. If you had a travelling companion , that would work best. My suggestion is to contact them directly via their official web. There are many options you can purchase on the automated vending machines for tickets .

Hi, siento no poder ayudar en ese tema. A parte de ver la ciudad desde lo alto de Duomo no tuvimos oportunidad de subir a ninguna otra altura
