I once did a basic course in this - it was a very nice 'social' group activity, take it in turns to lay hands on other members of the group. You're supposed to be able to heal eg relationships retrospectively through it, and the amount of money you pay for the 3 levels - basic, teacher and master - is supposed to be integral to the "energy flow" that is awakened. It's often done by people in other healing disciplines as a sort of ancillary thing. They also said that doing the course would get you into touch with what you really want to do with your life - I started practising the violin like mad again, and must now be one of the world's most accomplished amateurs. But my daughter always says I have really warm hands.
If you're getting personal attention from someone for an hour that's something we don't get every day and is 'really nice', so you pay for it of course, but you might also prefer to get personal attention from a "masseuse" with extras, whatever floats your boat!
