Hello. I would like to know if anyone has an idea what an appropriate tip is for one of the "free" (tip based) walking tours of Paris? We have never been to Paris, but I have been planning for our upcoming trip (May) for almost a year now. I have not read any suggestions regarding what to tip for this service, so I am inquiring here! I wrote to one of the tour companies and asked if there was a "suggested" tip range, and they said "no" - you pay for the value you feel you received. Well, in the U.S. I would have an general IDEA of what a good tip for this service would be; (2.5 - 3 hour walking tour with up to 25 people in the tour) - I would most likely tip $40-$50 p.p., U.S. for this, maybe more if I was absolutely delighted with the tour. Suggestions/personal experiences would be appreciated. TY!!
