My friend is going to be 30 in November and is wanting to do something extravagant for her birthday.
She wants to get some friends together and go away for a weekend but wants an unusual location like a castle, cave, treehouse etc.
She lives in Nottingham but has friends in Northampton, Birmingham and London so somewhere in the middle would be great but if not she's happy to travel.
Does anyone have any ideas for unusual venues? I want to make this birthday special for her.
