Why dont you book time off and go on one of those "last minute holidays" websites and literally decide day or 2 before! That would be pretty adventures, plus it should be cheaper!
Never thought of that! I will have a look and see what kind of deals are available. thanks for the suggestion
If you go to GB i recommend going to remote parts of Scotland or Wales. Stay away from cities its crap.
I'd go to the Grand Canyon and Antelope Canyon in Arizona, US. It's unbearable in the summer, so now is a good time. Should be cheaper than an overseas flight.
