I doubt the debt is over £5k - we’re talking about a holiday in a caravan.
I agree that it’s most unlikely to be anywhere near £5k. More like £1200 if it’s a popular park and the booking is in high season.
It’s still a lot to lose, and I do sympathise with the OP, but I think she’d be best advised to write off the loss.
The OP seems to have gone - I’d be interested to know whether she has approached the site owners, as there are a lot of unanswered questions.
As I say, the park where our lodge is doesn’t allow rentals, but people can let friends and family stay so long as no money changes hands. Are the rules the same on this park? It tends to be the big ones (eg Haven) where caravan owners can sublet, but many realise that the risks are high and the profits low, so stop doing it.
Has the new owner decided against renting it out? I don’t know what ‘codes’ are for, but if they relate to the use of facilities on the park the owners are likely to be interested if they are being fraudulently sold. Does the OP know for sure that the caravan was sold on the understanding that bookings would be honoured? Did money change hands at that point? Who got the profit from the holiday, the niece or the new owner? I know the OP was asked for more money- was that paid, or just a deposit?
