To offer helpful advice we need to know a little more: what kind of pictures you want to take and what you will do with them once you're home.
If you just want some holiday snaps as a reminder of a good time away, posting some to facebook, then most modern zoom compacts or even a phone camera would be adequate, if not great. If you want to try to create some better images that you might even want to print & hang on the wall, or you're going somewhere exotic that will need something with a longer telephoto/wider wideangle then that will make a difference.
