I would suggest not bothering with anything too fancy...a bunch of flowers and her favourite foods in the fridge will do nicely. I would also sit her down to tell her how much you missed her and how lucky you are to have her (if that's how you feel), I don't mean saying it in passing, but actually sit her down and make a point of meaning every word. Oh...and Al Maha because being in a long queue isn't much fun :-)
