According to a nice young lady Key Camp who I spoke to a couple of hours ago he should contact
www.car-transfer.itTheir site is in English and Italian so he can choose the language.
They quoted me between €108 and €123 depending on the size of the party
It seems that they (the girls at key Camp) always recommend
www.car-transfer.it. Chap by the name of Aldo Dinoble (sp?) runs it, so they tell me, and he does most of their work. The price the young lady quoted me was from Treviso Airport to the furthest of the three sites that they have in the area. That was done deliberately as it would be a longer journey and thus the price from Venice airport should be a little less. The young lady suggested going to the site and asking for a quote giving the accurate dates/times and numbers which I did not have. She assures me that the people at the Italian web site speak excellent English.
The young lady at Key Camp also told me that she and many of her colleagues catch the airport bus into Venice and then get a water taxi across Venice. Once off the water taxi she assures me it is a short bus or taxi cab ride to the site. This she says is the cheapest and pleasantest route.
I post this in a spirit of friendship not ridicule.
