Treviso is one of Ryanair out of town airports. Marco Polo is the nearest to town. The bus service to Treviso is pretty good though and a link to it is below.

From this website the cost to Mestre(where hotel is ) is 9 euros return. this bus stops in the same place as the bus to Marco Polo and is a few steps to the hotel/the train station to Venice. If youre Italian is as good as mine
the words "Orari delle corse" on the weblink above will connect to a file which if you download gives the times of the buses so you can seee if one meets your flight!The price of 320 euros is pretty good for two adults for four nights i think thats a good price when compared to other cities.
Never been to Prague would love to go though.
Karen- Venice prices can be on the expensive side unless you sniff out the Menu Touriste which are on in a lot of restaurants for about 14 e for three courses.
Hope this helps!
