The problem with this sort of 'prize' to an 'exclusive' destination is summed up in that very word. What is not included is excluded and exclusive. The price of a basic drink in a hotel such as the one it looks like they will be staying in would buy a round for 20 people at the local spoons'.
Same for food, and it's not as though there are any cheap bars or greasy spoons you can go to instead (and if there was, there is no public transport to take you there), neither is there a corner shop you can get cheap basics in. If you aren't able to spend hundreds of pounds on basic stuff, you could essentially starve in your 5 star hotel room.
I remember a few years back when Wig'n'Sleaze were flown out to Dubai to attend some sort of rally for whatever pyramid scheme they were in (the only trip they've ever been on, hence the repeated use of the pictures to portray their jet setting lifestyle). What the pictures actually showed was that all they were able to do once there was wander around in the hot desert air (the only people outdoors and on foot) and look in from the outside at the places they couldn't afford to enter.
Even if the accommodation covers basic meals, they will remain confined to their hotel for the reasons above. Sounds like hell. If I was a 'slightly successful' qualifying bot, I'd use any excuse imaginable not to go.
Same for the cancelled Australia GR that they were all raving about- 2 days' travel in cattle class, three days of jet lagged hell in forced 'training' and 'recognition' rallies, followed by another 2 days travelling back.
You'd have to be insane to see this as any kind of 'reward'...
