I have 4 weeks. I don't have to go to one particular place for that time period. Could come back to London in between. I don't really want to go on an 18-30 holiday, though I am happy to back pack around. I don't have a significant other to go with or any mates at the moment (who I know are free and want to come with me! I do have friends!!!!), so safety for a single female is one of my concerns, though I'm not a chicken. Any ideas gratefully received.
