As had been noted - depends on your purposes. The camera should match what you are planning to shoot, and how.
Some considerations:
1. What is your budget?
2. Will you be shooting in JPEG or RAW? Nowadays most cameras have the ability to shoot RAW, but I may be wrong. JPEG - if you are willing to allow the camera to have the final say as to how the shot will look. RAW - if you want to do creative post-processing yourself later.
I would strongly recommend shooting in RAW (unprocessed, uncompressed data). Even if you are not interested in/know nothing about software post-processing now, that may change as you learn more. And when/if you do develop the interest in working on your pics later - you will have RAWs from your trip that you can pull all kinds of color, light, and shadow info out of - when you are ready to revisit them. There is very little you can do with JPEGS, as so much data gets discarded by the camera in that format. At least, I would recommend shooting in RAW/JPEG setting, so that you could have JPEGs for now and RAWS for later if you ever need them. So you will need a camera capable of that.
3. Do you want interchangeable lenses or an integral camera/lens body? Interchangeable lenses allow you to play with all kinds of perspective changes. Or you can switch to a fast lens to let in more light at night for cleaner files. However, sometimes a single super-zoom camera will suffice for travel - especially if it can shoot RAW. See above.
4. Will you be mostly shooting in daytime or at night? In daylight a super-zoom will be fine. At night - not too good, unless the camera can handle high ISO values. So that's a consideration.
5. Are size and weight important?
6. Do you want zooms or single focal length (prime) lenses?
Sorry, didn't want this to turn into a primer on photography. I just don't know how much you do or don't know and your question was a bit vague. Hope this was a bit helpful.
Good luck!
