This is a very basic map to give you an overviewMy folks just returned from Italy, and said (and showed pictures) that there are verrrrrrrrrrrry long lines and waiting times to get into the Vatican.
Some suggestions I have:
Get yourself up to the Pantheon (or even further back, at the Trevi Fountain) and walk down to the Via dei Fori Imperiali from there, passing by the Vittorio Emanuele II monument, and once your back is to that, you're only a few steps away from The Forum, and a very short walk from the Forum to the Coliseum.
AND/OR
You can walk around the Vatican perimeters and there is plenty to see, then stroll along the river passing Castel Sant'Angelo (The Mausoleum of Hadrian). It's a gorgeous walk, and if you're into handbags/wallets along with interesting bookstalls, you can haggle for some great deals
AND/OR
there is a Metro stop just around the corner from the Spanish Steps, which puts The Borghese Gardens just behind you, and Piazza di Spagna down in front, leading to *Via Condotti, which is the 'most fashionable' street in Rome (all the top designer shops), or, around another corner a few short blocks south, you'll find the Trevi Fountain. And very close to that, you'll find the Pantheon.
AND/OR
If you like the kitties, the least heartbreaking and more interesting place to see them is at
Largo Argentina, an old ruin in the middle of a busy traffic square, but closed in, which is also a cat sanctuary (with a 'no-kill' policy). You can see the ruins and the cats from the street as you walk by, or there are specific hours you can go in. And whattya know, it's just around the corner from the Vittorio Emanuele II monument (also known as the Wedding Cake)!
It's fairly easy to get to places, and just by walking around the city in general you can see loads, as lots of things are fairly close together. It's deciding how much time to spend
inside somewhere once you get there that is going to be your bigger issue (somewhere like the Pantheon is not a long visit and you can go straight in). The Metro is efficient, but not expansive (I think there are 2 major lines, A & B - and a few that spring from those), and covered in graffiti. I don't know about passes.
Here's a link to a map and info
Take in what you can, take notes, look at this as a 'sampler visit' - so you'll know a bit better what to spend time on next time!
(Yes, I LOVE, LOVE, LOVE, LOVE, this city!)*
