I got a Sony RX-100 for trips, I recommend it, the image quality is great and it has quite a bit of zoom (though I forget the exact lengths).

I also have a 5D, and the 95% of the difference between the 5D and the RX-100 is the increased ergonomics, so if you aren't shooting seriously/professionally, you don't really have to bother with anything above a cheap, good Sony.
