One of the two covered parking lots in Venice is on the Tronchetto Island. Right at the end of Ponte della Libertà, the bridge that connects Venice to the mainland, at the stoplight take a right turn and follow the indications for Tronchetto. The Hotel is approximately 2 Kms. away and may be reached by a taxi motorboat, at the estimated a 20 minute trip that takes you right in front of the Hotel - or eventually the public vaporetto, line no. 82, (bulky luggage must also pay ticket).
The other parking lot, Garage San Marco, is in Piazzale Roma. Instead of turning right at the stoplight, stay on the road and continue straight. It is suggested that you take a taxi motorboat, or the public vaporetto, the stop is San Zaccaria; depending on the vaporetto line, there may be a bridge to cross. For those who have a lot of luggage is suggest a taxi.
