I'm going to be going to Santorini for a couple of days after a small trip to Athens this summer. I've never been before and I really don't know where to start. I'm going to be travelling alone and looking to see the size and pretty much anything that Santorini has to offer. I'm not too picky when it comes to hotels and restaurants, so any advice that you have from your first hand experiences would be great. Also, if there are any extremely touristy areas that I need to avoid during certain times, please let me know.
