I didn't forget that my random Rome ramblings were not done, so here's some more:
Particularly on a first trip to Rome, I would definitely recommend getting a Roma Pass. I think it cost 25 Euros (each person needs their own card) which gives you, over the course of 3 days, two entries into participating museum or archeological sites (discounted admissions beyond those two) and all public transportation. We earned our money back with entry to the Colosseum (12 Euros?) and later the Baths of Caracalla (6 Euros), plus more than a handful of subway rides (2 Euros a pop?). It would have been worth the price of the entire cost of the card alone, just as we were able to use the special/designated Roma Pass line at the Colosseum... which we pretty much walked right into, passed hundreds of people queued up and I'm guessing at least an hour's wait. The hard part was finding where they sold the passes. We heard they were on-sale at the Termini train station (where we came into Rome), so we were looking for a Roma Pass kiosk, but it ended up just being sold at an ordinary newsstand. Also, it was great being able to just hop on and off the subway. We did A LOT of walking in Rome (and Italy in general), so it was hitch a ride whenever we could...
Speaking of the subway, it is a not a very extensive system (I imagine it is a archeological nightmare digging anywhere in Rome!)... or confusing... just two lines, crossing at Termini, which good for us was right near out hotel. But a lot of the major sites are at subway stops... Colosseum, Spanish Steps (Trevi is nearby), and the Vatican. But as with most subway systems, it is very well utilized, I think we only were able to sit down one or two times.
The craziest place we visited on our entire Italy trip?! The Vatican. Before our trip, my friend Jen had warned me that the Vatican was ironically the worst area for pickpockets... for us, unless we are missing something we haven't realized yet, it was the craziest place just for the masses of tourists that were loud and somewhat pushy. While the long line moved fairly quickly to get into St. Peter's Basilica, it was still crazy... and my enjoyment of the famed Vatican Museum was seriously inhibited by the crowds as at times it felt like we were being herded through it like cattle (and we were there mid-/late afternoon which allegedly to our guide book said was the better time to go). The capper was being all corralled into the highlight of the Vatican Museum, the Sistine Chapel. There were so many people in there that it was really hard to move without much elbow room. There was supposed to be respectful silence in the chapel, but that was hard to accomplish with the rumble of thousands (??) of people and then above the guards having to yell over that rumble to "keep moving" or "no photo!" ... occasionally interspersing loudly "ssshhh!!" shushing. Again crazy, but a bit comical as well. That said, still a recommended/necessary stop while in Rome... and I would definitely recommend this be one of the place where you get an advanced ticket. We did and once again, were able to skip a pretty long line for same-day entry and they have it set-up to deal with even longer lines than what we saw. BTW, there is no entry fee for St. Peter's Basilica (just to climb the dome or go to the crypts and maybe some other stuff that we didn't have time for... next time!), the Museum cost about 14 Euro (+ service charges if you order online beforehand, but again well worth the shorter wait time).
The strangest thing we saw in Rome (and probably our entire Italy trip) was not something we particularly set out to look for... but while in Piazza Navona (which is a must see) was going inside Sant' Agnese in Agone church... back in the sacristy (the "sacra testa" according to the guidebook) is "chimpanzee sized skull of St. Agnes, martyred here in the 4th century." It was really odd and personally I find it hard to believe it human skull as it could easily fit in the palm of one's hand ... or do skulls shrink? Anyhow, very odd ... very Ripley's Believe It or Not (maybe I'll get pummeled by a lighting strike, but I am more the latter).
Finally, had a pretty cool Italy experience thanks to this very blog. Shortly before I left, I wrote up a blog entry for Paula Butturini's memoir that I read largely because it took place in Rome (though that was not the point of it, neither a travelogue or a "life in Rome" book)... and while we were at the Philly airport waiting for our flight to Venice, I checked my email and there was a comment left on that post by... Paula Butturini! I kind of write this blog in a void, knowing it'll be read by some of my regulars and perhaps a "drive-by," so it is always a bit embarrassing to hear from the person your post is about! While I knew I was complimentary of the book, I still worried about what I wrote and while there was cringe-y thing here and there, overall it was not too bad. Anyhow, Paula recommended a gelato shop Trastevere, one of the neighborhoods she lived in while in Rome. We did find it (it kind of felt like an Amazing Race challenge), but unfortunately it was closed for renovations. After we got back, I did email her back to thank her for her comment and tell her of our attempt to find the shop and she very kindly (and quickly) replied back to that email. So a very cool moment that would have never happened if not for this blog...
and that's probably a good way to end this random Rome ramblings, unless I get some crazy brainstorm (probably as soon as I hit upload, I'll think of something else), but if you have any specific questions or asking about a particular place, I'd be happy to respond! Grazie, ciao!
