Just returned from my 7days Best of Rome trip. Our Hotel (Lancelot) was within a 3min walk from the Colosseum. Our tour guide Nina was incredibly kind and joy to have around. Our local tour guides were also kind and knowledgeable as well. You can check out my previous post on Paris (https://community.ricksteves.com/travel-forum/tours/best-of-paris-7days). Having been to Paris I was familiar with the public transportation system. If you want to see some great ruins and churches and be able to see a lot in a short time this is the trip for you. Many of the historical locations are all within walking distance of each other if you're willing to walk at least a mile or two.
SCAMS - like any European countries there are people trying desperately to sell you anything. Do NOT take pictures with the "Gladiators" by the Colosseum, they will ask you for money or take your phone and hold it ransom for money to give back. Anyone walking up to you that looks out of place, usually they are and are gonna try to scam you. Just say "no" confidently and they will usually walk away.
Transportation - I flew into Fiumicino airport and for 14Euros I took the Leonardo Express directly to the Termini main train station NON STOP. I also took this from the hotel to the airport as well. It gave me 32minutes to gather my thoughts before and after my trip. There are plenty of ATM/MAC machines in the airport and you can purchase tickets at the red kiosks located. Just make sure you get them stamped at the egg shaped white machines before you get on the train. From Termini select the right train to your destination. very easy. If your hotel is near the Colosseum then take the Metro A to Laurentina(final destination) and get off the 2nd stop which is Colosseum, cost is 1.5Euros.
Gifts Goodies - buy them from the vendors in green kiosks or stores. Don't support the people just sitting there.
Tours - You will see a lot with this tour, but if you want to visit some of the major churches you'll have to do them on your own. And I highly recommend you do. St Peter, St Paul, St Giovanni and many others.
Vatican visit - We had the pleasure of seeing the Pope on Wednesday morning for a quick morning service. ADVICE ... if you want to get close like 5-8 feet away, take seats on any, ANY chairs near the borders. He will make his rounds on the road around the chairs.
Food-Restaurants - YOU must eat at least one of the following while in Rome - Cacio e Pepe, Lasagna, Suppli, Carbonara, Amatriciana, and of course gelato. If you go by the tour book and you see "reservations available" make one. Best meal for me was at Trattoria da Enzo, I waited 75minutes for a table for 1 and it was worth it, make a reservation if you want to eat there.
Walking/Steps - Like in Paris I did some extra walking on my own, if it was inside of 2miles I walked it. Took in the sites and sounds and smells of Rome.
Packing - As you travel more you realize what to take and what to bring back. I did my bulk of souvenir shopping at the Vatican Museum thus leaving me a free mind to explore.
Spanish steps/Trevi Fountain - HEADS up these two places are super, SUPER crowded. If you want to get a nice picture without anyone there better get there about 6-7am or after 11:30pm other wise it's a mob of people.
Final notes - Be polite, use your "Please" and "Thank you" in Italian it will get you far. Remember we are a guest in another country. I am looking forward to my next trip. Go with a positive attitude, leave your bills and frustrations back home. Enjoy your visit. I say that because last year I saw and took a nice tour of Notre Dame Cathedral and a few months ago it burned down, almost.
I hope this helps anyone about to go to Rome. Best wishes sorry for any misspelled words/locations/names.
Thank you Rick Steve's and Nina and rest of our tour guides.
