Kirstey (and anyone else who is interested) - we've got a training captain who taught us (very wisely as it turns out) to rehearse the go around at the 1000' call in your head. The go around procedure should be included as part of the descent brief, but that could well be 20 mins hence - so by doing this "rehearsal" you're prepared for it, preventing a clatter of bits when ATC or yourselves decide to actually do it. Worked a treat a couple of months back!!!
As an aside, there are many gotchas in an all singing, all dancing new generation aircraft if you're not careful!
