My weekly lesson is 30 minutes and is part of a continuing $35 per half-hour package of 10. I always come early to tack and muck, so she typically lets my instruction time run 45 minutes or over.
I then untack, groom and spend an hour sweeping/cleaning out the stable. I obviously don't have to do the extra work, but it allows me to spend more time with the horses.
Being with them is like a gift to myself.
