It is a very good service to give you an idea of the available tours and it is very easy to book and communicate. i asked a few questions and I received a response promplty both via emails and via chat. The selection of tour operators is relatively limited but I haven't found many more otherwise at least for the destination I was looking for. I'd like to see more tours for "over 38" as this is quite limiting. i am 45 and I still want to travel, adventures, and all other things including partying sometimes... and at good prices and not needing luxurious hotels or extreme comfort - it is not tourradar's fault but maybe more tour operators are available out there.
