I used the 50mm on the 1d a bit, and its a decent walk around lens, gets fantastic shots but it is quite a narrow field of view - still, you just have to compose your shots in a different way I guess. indoors its not really very good since you can't control where you can be (cant get far enough away to fit things in the view)
If I were taking a camera on holiday, I would take my Nikon with the 18-70 lens as it does it all. When I go out, sometimes I will just take the nikon with the fisheye though, its fast (F2.8) and gets EVERYTHING in the shot - plus its a mad lens, which is funny.
Nikon make a 18-200 VR which is supposed to be very good, but I don't think there is a canon lens like that.
