Ok, so I want to do a half day trip out to Tivoli and Hadrian's Villa. I will be on a slight budget and I'm sure the metro/bus combo out that way is cost effective. I'm just still confused about the exact way to get to Hadrian's Villa from Tivoli. I've read roninrome for detailed directions to Tivoli, but the directions to Hadrian's Villa is still a bit confusing. Any help? I'm not afraid of venturing on my own and am pretty good at knowing my way around, just as long as I have the proper directions.
I also wonder, how much time it will take to see both sites if I decided to do this without a tour. Or is it better to pay the roughly $80 to go with a bus tour? The only problem I see with that is the tour only lasts 4 hours (I'm assuming that includes transportation time?). Any advice will help.
