If you want to be 100% sure about your free tour taking place, text or call Ben: +32/486327292. This is by far the best option. Please note that as a freelance guide, I do the very best I can to avoid free tour cancellations.
I normally announce free tour cancellations and holidays in the contact section of bensghent.be and on my facebook page: www.facebook.com/bensghent/. I also inform Hostel De Draecke, other hostels & hotels and the Tourist Information Office Visit.
