Recently, I jst came back fm Rome/Florence/Venice and I would like to share my experience with u so that u are better prepared and hv a more enjoyable holiday.
Colosseum/Forum - To avoid the 1hr Q at the Colosseum, u may want to visit Forum first and purchase the entrance tix there which includes Colosseum. If for any reason, u visit Colosseum first, keep the tix and use it to enter Forum on the same day.
Accommodation - Do yr homework here and book yr hotels online. I would certainly recommend UNA Hotel - 5Stars for Location, Room and Service.
Vactican City - this city is hell of crowded on weekends, highly recommended to get yr tix online too. With the vouchers, u can proceed directly to the entrance - DO NOT join the regular Q (upto 1km long during weekends and peak period).
Toilets - Public toilets are very few and u need to pay 50cts Euro to 1:80 Euro to pee…
Lookout for McDonald (beware of long Q esp for the ladies), Café(not all provide toilet facilities, asked first), Restaurant or Internet kiosks.
Transports - although many tourist recommended the 1Day Pass (4Euro) or 3 Days Pass (12Euro), I would recommend u to buy the single trip fare (1Euro); what I did was take the Metro train to the furthest attractions eg Piazza Popolo and start walking to the rest of the attractions towards city or where yr hotel is. Most of the attractions are within walking distance. I did that many times…
Meals - most pasta/pizza are around 8-10 Euro, portions can vary, so just look around before u place yr orders. Cappuccino cost around 1:50Euro at Bar and upto 6Euro for table service (same size)
Gelato (ice-cream) - there are many but not all are good….I would recommend u Giolitti just a short walk from Piazza Navono http://www.giolitti.it/english/home.html
If you happened to be at Fontana di Trevi, give Gelati-Pizza a go.
