It is safe to say that everything in the center of Pisa is within walking-distance from everything else. Both the suggested hotels and the conference center are in the center of town.
The only place you will probably use which is not in the center is the airport, which however is just 5 minute away by car. Although there are buses (and trains!) going back and forth between town and airport, at arrival the best thing for you to reach your hotel is probably to get on a taxi, which will cost you about LIT. 15,000.
After that, you will probably be moving on your feet until departure. Here is a table of approximate distances (in minutes of walk) from the hotels to the Congress Center and the Computer Science Department (in case you want to go and visit some of us).
|Hotel||Cong. Center||CS Dept.|
|Jolly Hotel Cavalieri||15 min||7 min|
|Hotel Duomo||25 min||12 min|
|Hotel D'Azeglio||15 min||5 min|
|Hotel Kinzica||25 min||12 min|
|Hotel Verdi||7 min||7 min|
|Hotel Minerva||7 min||7 min|
|Hotel Royal Victoria||15 min||2 min|
|Hotel La Pace||15 min||5 min|
|Hotel Ariston||25 min||12 min|
|Hotel Cecile||20 min||15 min|
Thus, the hotels Verdi and Minerva are those closest to the conference site. On the other hand, the hotels Duomo, Kinzica, Ariston, and Cecile have a view on the leaning tower.
