Edinburgh is much fun wandering around that you could think that there was no need to actually arrange anything specific. Well, you could! The trouble is that groups have a habit of losing their cohesion and there is the dreaded lunchtime glass of wine turning into a bottle or three with the result that half the gals are completely blotto before you have even started.
The solution is to plan a few things to do. Your choice is pretty amazing and it all comes down to the style (and ages) of the group and what you want to remember! You can go for the common garden hen standards like a lounge by the pool in a spa or you can go for something you have never done before and which will be long remembered.
