Trying in the right forum this time!
We booked our tickets to Borghese last month, for the 13:00-15:00 slot on Friday April 27th. We now have tickets to the Colosseum Underground Tour booked for 16:05. This timing is obviously far from ideal, we booked the Undergound Tour simply as back up in case there are no night tours this year - and with April just 2 weeks away, that seems increasingly likely, sadly.
My question is, would 15:30 be early enough to arrive at the Colosseum? We'd have to pickup our tickets and go theough the security screening, could all of that be done in 30-35 minutes? Or are we going to have to cut short our two hours in the Borgehse to be sure of being at the Colosseum even earlier than 15:30?
