I've been following the Yemen situation fairly closely on Twitter and no, I'd definitely not consider going at the moment.
There's been a recent change of government in Sanaa with subsequent unrest, although that does seem to be improving, slightly.
In Aden, since October 14th there have been demonstrations in support of re-separation. October 14th is, of course, a significant date in the south because it is the anniversary of their independence from Britain and that is why they picked that date to start the Southern separation push this time. Up until today it had all been very peaceful, but sadly Twitter is currently reporting the death of a five year old child in Dhalie caused by "indiscriminate gunfire from Yemeni soldiers toward market". Whether this was an attempt to break up protests or just a sad accident hasn't been made clear yet, but what is pretty clear is that nowhere in Yemen is really safe for anyone at this time.
