We are a group of 8 adults traveling from May 5th to May 19th in Italy..Florence (5days)..Montepulciano (5 days)..and Rome (3 days). We have all our flights and accomodations booked and are now building our initerary. I know that the weather in unpredictable but would it be likely that we could wear walking shorts and sandles during our day tours or will it be to cool that time of year? As we are all travelling with one suitcase(26in) I don't want to pack things that will not be used therefore your opinion will be most valuable..thanks Laurie ...p.s. will be sharing our itinerary plans for your expert advice soon.
