Yes there are toilets on the coaches and when we went the coach stopped halfway at a service station...our guide also showed us where we could use toilets in Florence itself. (I remember one through a handbag shop on the huge square in front of Santa Croce church!!!) Funny the things we remember!
No replies needed now thanks, I found all the information on RCI website - sorry!
I do have another question regarding the trips. We are due to dock in Livorno and hear it is about a 2 hour transfer to Florence - on the organised trips are toilets provided on the coach - I get really nervous travelling when I don't know where any toilets are.....
No the coaches dont have toilets. If your worried to go Pisa instead, a much shorter coach ride about half an hour and Pisa is very interesting.
