I was lucky enough to win a credit on a tour through one of TourRadar's facebook caption this promos. When I won, I did a little happy dance, immediately followed by the dread of, "oh I wonder if this is one of those things where they make it so hard to claim the prize that they don't have to fork it out" Well I couldn't have been further fro the truth, Carla emailed me straight away saying to have a look and let her know when I wanted to book and they'd apply the credit. And just like that (well once I got some more leave from work!) They sent the link with credit applied. Just so easy! You can tell you're dealing with real people not computers or mass trained mindless customer service reps.
