Kathy, when we were in the area of Santa Scala, there was a terrible downpour with hail. It would not have been fun walking to that Giovanni Metro Stop, especially when we got turned around and lost our bearings so much. We didn't have Google Maps, just a good ole National Geographic Map that I didn't dare take out in the rain, for fear of ruining it. We did ask some people with phones for directions, and they'd try to help, but often they would tell us to go the opposite direction we should have. They had trouble reading their phones' directions, I guess? Luckily, when we were ready to go, that Rome/Vatican bus was right there to pick us up.
As I've stated, hubby is O-L-D, and his hips were hurting him some on this trip, as he wasn't used to so much walking. Often, we'd breathe a sigh of relief when we realized we had Hop On/Hop Off tickets and could put up our feet for a while, with room to breathe and space. We could rest, relax, and enjoy the sights and sounds and hustle and bustle of the city in comfort. We liked the Open Air top the best, fresh breezes. The HoHo would often remind us of places we hadn't yet explored in depth, and we'd do so afterwards.
The problem with public transportation was it was crowded and bumpy. I was thrown into a woman who was irritated by that. I can't find my balance well on a crowded bus, holding a pole. And then there are the pickpockets we had to contend with... I'd rather pay a little extra for the luxury of the Hop On/Hop Off, even if it is cheesy. The Metro is much better than the bus, but often we didn't feel like walking all the way to a Metro Stop, especially in the pouring rain. I'll bet we walked at least 10 miles per day on this trip. It didn't bother me, except for the fact I came down with laryngitis early on, from a bad cold I had before we left on the trip, and when we'd get into our hotel at night, I'd be totally exhausted and just collapse, from my immune system being low, I think. I would have liked to have had the energy to research our next day's explorations in advance, but I was just too darned tired.
That said, next time I'd like to ride the bus into unexplored areas of non-touristy Rome, and see even more. I wonder where that wrong Appia bus we got on goes to, for instance? It wasn't crowded, but a nice man on it told us it was a different bus we needed to get to the Appian Way. I would also like to take all the Metro lines. But I still want to ride the Big Bus one more time. It was my initial introduction to Rome in April, and I have Rome-anticized it. Smiley Face for Kathy.
