I would say do it.
I never did it, but then again I am a fully qualified first aid instructor, with almost 15 years of experience teaching, and doing voluntary first aid work in a huge variety of places.
Basic first aid is a must for everyone in my mind

Now if you were closer, I would be saying to use my dad as your instructor - teehee give him some business ( he runs his own business doing first aid instruction amongst other things)
