Thank you Johan. I called them and they gave me confidence to use them so I will give it a go. The shots are $375 here and ~$50 there, times two for me and my wife. Its worth the slight risk that the plan fails. At that point plan B is to go into town to get the shots, a PITA but not the end of the world.

Bhomburg- we don't head out for Kenya for ~17 days. Thanks.
