Possible UK travel?

This is all very nebulous and only-potential at the moment, but there's a possibility I'll be included in an audit team being sent off to look at a couple of our suppliers' facilities in Puerto Rico and the UK later this month. (The audit is related to one of my investigations.) If so, I'll be tacking on at least a few vacation days while I'm there. (In the UK, that is.) More later if it becomes more solid, but my impulsive inclination would be to structure my "free time" around visiting people rather than things.
