i want to travel from Cardiff to Vancouver, but not by air... help?

hi there,

this is only theoretical right now, but i want to head out to visit a friend in Vancouver (maybe in the summer) but I don't want to fly.

I realise this is making life very very very difficult for myself. I can sort of deal with short haul flights in Europe, but the thought of flying to West Canada makes me feel a bit pale and shakey...

Anyone done this before? Any ideas where to start?

take a cruise there
