Just to allay any concerns, my plans for the week are:

Client meets me at BOG, takes me to hotel.

Client picks me up at hotel every morning and drops me off at night.

I'm planning to take meals at the hotel unless the client takes me out.

Client picks me up at the hotel the morning of my flight out and takes me to BOG.

I have already made arrangements for all of the above.

Overly paranoid? I don't think so, given what I've been reading here and elsewhere about Bogota.

It's not my preference - I would much rather go around and explore. But when the often devil-may-care Lonely Planet http://www.lonelyplanet.com/dest/sam/col.htm kicks off its description of the place with "...although the violence, cocaine cartels, and guerilla insurgency are very real, they do not necessarily impact on the personal safety of travellers..." it sure makes me concerned. (I love the way they put "do not necessarily" in that sentence.)
