In reply to Edradour:
Well, it depends on what you both want...
My honeymoon was spent up in the Northwest of Scotland. We had a great time. I recall two nights in Strabeg bothy having climbed at Creag Shomarlie (very nice) -all by ourselves, and a night sleeping in the back of the car infront of the police station in Kinlochbervie after a night out in the only opne pub in the Far Northwestern Coastal Highlands!
It was great, so I think it depends on the demands/desires/likes of your wife to be - I like climbing, bothying, being in the hills, I don't think I would have enjoyed an afternoon in the beauty saloon /spa - wedding or not (sorry Edradour).
So, my advice would be, what does your girl like and what does she want...find out and deliver accordingly! You can't go wrong.
