A friend of my, just leaving for rome, asked if I'd give her a few good tips, as I just returned . Thought I would share my experiences on TA
1. Take a good guide book if you have room in your luggage
2. Buy a small international data plan for your smart phone and down load google translate. Though most people speak English, I found it very useful when there was a language barrier.
3. Down load citymaps2go. It gives u gps without using data. Google maps works too, but sometimes I'd lose the map...having gps will save you so much time!
4. Take an umbrella. It seems to be sunny most mornings, but clouds up in the afternoon.
5. Bring a recyclable shopping bag. I used it to carry my umbrella, rolled up rain coat, groceries, and gifts. Grocery stores charge for plastic bags. And the recyclable fabric bags are really lightweight.
6. If you use sugar substitutes,, bring some packets with in your purse.
7. Bring Tylenol and tums. I had a hard time finding them.
8. Be sure to buy tickets in advance for the attractions. Otherwise face huge lines...
7. If your there for a while and will using public transportation... Get a pass of some kind. IMO, even if you spend a bit more for a pass, it is just so convenient! Worth the extra for the time it saved me.
8. Don't tip! You don't have to and it's not expected. As was recommended on this site, I did not tip at all. I still was thanked, and never made to feel bad about it!
9. Tap water and fountain water is totally safe to drink.
10. Pay with euros if possible to avoid hidden fees.
11. There is an ATM at FCO when you are near the exit to the street. It's against the wall in the lobby area
12. When waiting in line for a cab, don't let anyone steer you away. Stay in line...
13. Don't be alarmed if it seems the cab driver is taking you for a ride. Due to all the pedestrian zones and traffic, it may appear he is going out of your way. But mostly he is not. Ask before you get in, how much he thinks it will be.
14. The city looks bigger on the map then it is. Providing you don't get lost, and either have gps or a good sense of direction and are in good physical shape.., you can walk almost anywhere. I even walked to St. Paul's outside the wall! If not, don't let the busses and trams intimadate you. They are very easy to use. Just hold your purse close to you.
Hope this helps someone!!!
