I booked a tour through Tour Radar and had no problems or complaints. The customer service was great. The only thing I would say is that I got offered the Tour Radar app, however, everyone else on my tour got offered the G Adventures app before they set off. We all agreed it would have been nice to have got in touch with each other prior to the tour, however, as they didn't know about this app (as they didn't book through Tour Radar) and I didn't know about the G Advetnures one, we weren't able to. It might be nice to offer both to all bookings to ensure there are ways to communicate. Thanks!
