Great forum here with some great information from people, I've learnt a lot in advance of my trip. I'm doing four days in Rome from this Saturday, and as I'm travelling alone I'm trying to cram as many sights in as possible to keep me entertained :)
I've read a lot about some long queuing times in Rome, and while I don't mind a bit of a queue (an hour ish) I'd rather not spend half a day in one.
Therefore, can anyone tell me the sights that have notoriously long queues? I know the Vatican museum can involve a 3 hour queue so I'll definitely be pre-booking that to skip it; however are there any other notable ones that I should pre-book for at this time of year to avoid a long queue?
