we flew by ryanair valentines morning and arrived in treviso airport. we then got a taxi for €20 into treviso town and stayed in a hotel called "the casier hotel",it was very nice and peaceful also very comfortable, but it a small bit outside the town itself about 15 mins, but the bus is very handy as it come every ten mins. you have to go to a shop and buy a bus ticket which is €1.20 and one for your return journey..
then we went to the train station which in trevisio also and it costs €4.00 to go to venice and it takes bt 20 mins on the train. when you arrive in venice andwalk out the door of the train station, everything is in front of you. its beautiful. there are lots of side streets to walk to get to the big square and the rialto bridge but its very well signposted. you cant get lost..we didint go to any of the other places that colleen talks about so i a cant help you there sorry!!
