I read both Rick's book and another on Iceland and both said, "no tipping." But I have a tour guide who will be helping us for three days. I splurged, but I think it will make the trip more enjoyable for my elderly mother.
Anyway, I am trying to figure out if I should tip him or not. And if so, how much cash I need. He owns the tour business himself, so he's not an employee. Would doing something like treating him to lunch each day be a good tip (he will be with us at lunchtime each day he's with us)? Or should I give him cash? If so, how much? If he's good, a positive review on TripAdvisor or other sites is a given. That's how I found him in the first place. Thanks!
