Thanks for your replies, Muscat was a new one to me, but does look nice, and I was thinking of Dubai as an option too, not sure how much shopping I can handle though!

I've looked a little further and noticed a very good Avios redemption to Bahrain as an option, and also like the look of Amman for a trip to Petra (we spent a month in Egypt in the past but never made it over there).

Decisions Decisions.... thanks again!
