Bicycles on european trains

I left Patra by boat at 23:59, it took 32 hours to reach Venice, it was a pleasant trip sailing up the Adriatic back past Albania and Croatia etc. An inquiry at the train ticket office in Venice is where I was told no such journey was possible with a bike to Paris unless it was in a bike bag. I tried to get such a bag in few other city's but Venice isn't a city where there is even a bicycle shop that google knew about.
I got a train to Milan a bigger city with many bicycle shops I was hoping to buy bike bag there but instead of spending money looking about for a suitable bag I jumped on the next train to Geneve, booking this ticket wasn't that simple. After queuing for a little time to buy a ticket he had found a train taking bikes but every time he hit book trip the computer crashed, in the end i was issued with a handwritten slip to produce to the guard on the train for my bike and by 21:00 I  ended up in Geneve via high speed train, while on board I got chatting to nuclear scientist that worked at cern.

I Then booked into cheep hotel in Geneve so i could get 7:41 to London. They could only get me as far as Paris because all the trains are booked out to the UK till after Dec 25 so I guess its a train to Calais and the boat to Dover unless the eurostar bike service is not booked out better give norm a call when I get to Paris.

Venice

The boat trip from Patras to Venice went well food and coffee was of a ok standard for a boat but a little expensive. I couldn't see any signs from Venice port to the train station in Venice which seemed a little weird altho its only half a kilometre away but found my self cutting through the train works yard to get there, then a couple of engineers showing me the cross rails route to get to the station very friendly bunch. Upon arrival at the ticket office I was was informed that there is no solution for getting me and my bike to Paris with out a bike bag. So i brought a regional train ticket to Milan where i hope to be able to buy a bike bag at a sensible price unlike the 229 that i found in Patras. Theres snow on the ground here in Venice and its a little brisk probably get  hotel in Milan and work out my options but one other thought was to hire a car and drop it of in Paris which would save having to buy bike bag and a hotel.
