wrong type of vehicle pass

As a newbie, i am making lots of mistakes with tickets but you live and learn.

Was overjoyed to pick up a campervan pass on twickets but now found out i should have got Motorhome pass for my trailer tent. 

Any idea how strict GM are on this? I will actually be on site as a settler with a small tent for the first 3 days, so maybe this is an opportunity to resolve beforehand. Or maybe i can just drop my trailer tent on Thursday and stick the car back in the blue car park?

Next time i know to be a bit more on it (and early).

Any thoughts appreciated. Just dont want to be turned away with my trailer tent on Thursday.

or if anyone has a Motorhome pass instead?
