I have to go to Edinburgh for work later this month and have a WHOLE CHILD-FREE EVENING all to myself! 
What can I do (apart from drink lots of lovely wine)? I will need want to be in bed by 10.30pm as a whole night of unbroken sleep will be a dream come true and is an opportunity that must be maximised, but what can I do between 6 and 10?
Grateful for any guidance!
