I wanna share this great tip with you.
I was recently on a business trip to Italy and I found myself with an extra day in Rome. I had never been there so I was looking for a way to see as much as possible of the city in less than a day. Googling up and down I found a guide to see venice in just one day!
It was only 4 buck so I bought it and I immediately received it on my email and they also gave me a free restaurant guide. The guide is very well made, with tips on how to avoid long waiting times at museums and what to see and what not. I was very happy beacuse I was able to see Rome in just ONE day. Rome is beautiful, you MUST see it, it's one of the best cities in the world. The Coliseum, The Imperial Foro, The Vatican, I basically saw everything and it was incredible.
Btw, here's the website: www.onedayguide.com
They have Venice, too. I am going to buy it just in case I'll find myself in Venice.
