I will be there from the 20th to the 26th. Shall we meet by the Trevi Fountain? 
I have no idea where that is, but I will definitely be in Rome on the 21st (flying out the 22nd.) If there’s wine in it for me, I’m there! 
Out of curiosity, are you flying USAir to Rome? I did a trans-Atlantic flight with them a few months ago, and the Airbus’ they use for that flight are great–even in coach.
Ack!..another Rome thread…I’ll go ahead and point you here for some good general tips, as well as some specifics about Rome.
I personally don’t think 5 days is nearly enough time to spend there. I’ve been to Rome 4 times now, and still am constantly finding new things to see/do/experience. A day trip to Pompeii is a definite must just be sure that you know exactly where you’re going. I had forgotten that when you buy rail tickets in Italy, they go from one main stop to another. So your ticket will say something like Naples -> Sorrento or something, and you just have to know to get off at Pompeii. Depending which station you get off at, it’s either a very long walk, or a very short on from the train station to the ruins. Ask at the station and they’ll let you know.
You said you had 5 days in Rome, so I’m assuming that you’ve taken off the day you arrive, and the day you leave, and have 5 whole days in Rome at your disposal.
While some people don’t like to plan, and sort of like to wing it, there is so much to do in Rome that a little planning can help make your trip more rewarding. For example, try and group the things together that are in the same location.
Seeing St. Peter’s, the Vatican Museum, and the Sistine Chapel is basically one full day. Sure you can run through the museum to get to the Chapel, look at it for a few moments, and sprint out…but there is so much beautiful artwork to see that it’s a shame to do that. Although if your daughter doesn’t like art much, it might get to be a bit repetitive for her. Do see St. Peter’s first…take a few moments to just stop and look at the plaza outside, and get a feel for it’s size. Then walk inside, and stand in awe of the majesty of the building.
Another day could let you hit Piazza Navona, Piazza Colonna, the Trevi Fountain, and The Pantheon. They are all very close to each other, and if I might recommend a nice restaurant, La Rotunda right next to the Pantheon is nice. We eat there all the time. It has a nice blend of touristy and local, without taking too much advantage of you. Avoid eating anyplace within a 5 minute walk of St. Peter’s at all cost.
I’m sure you’ll be seeing the Coliseum and Roman Forum, but if you have the time, just up the street from the Coliseum is the fairly recently excavated site of Nero’s Domus Aurea. I thought that was a pretty cool tour. It’s eerie to walk underground and see rooms that have been buried for around 2000 years. Also not far from there is San Pietro in Vincoli that has Michelangelo’s Moses which is a pretty impressive piece of sculpture.
Your daughter might like hanging out by the Spanish steps while eating a gelato, at 16 she may have started studying English Poetry. If so, she might be interested in The Keats-Shelly house. If she enjoys that, I highly recommend that you take the time to visit The Protestant Cemetery where Keats is buried. His headstone is a very touching site, and the nearby Pyramid of Caio Cestio is very cool as well.
I could literally go on for pages and pages and pages. Rome is just more than one person’s mind can wrap itself around in one visit. Go…walk…explore…enjoy the city and appreciate it’s history. Don’t overdo it, or try and fit too much in during one day. Take a couple hours for a short nap, relax, then go out for a nice dinner and a walk down the Via Corso for an evening stroll, or closer to your apartment is the Piazza Navona. Full of evening street performers, artist, and vendors, it’s a great way to end an evening.
Have a great time, and if you have any other questions, feel free to ask. I’d advise getting a couple of books and just thumbing through them. Look for anything that catches your eye, and then read more about it to see if it’s something you’d like to see.
Thanks to everyone for all the information you’ve given me.
I have been following the other thread as well,** Atreal**, but that thread was actually started after mine.
Yesterday I called the apartment rental place in Rome to confirm our reservation, and I’m glad to say they spoke English very well. That means I’m set for my flight and I’m set for my accomodations; all I have to worry about now is finding something to eat while we’re there. The rest we’ll just play by ear. I think, from what’s been contributed to this and the other Italian thread, we’ll be OK. I can’t wait!
