With the Mellor's deal all but confirmed to have fell through from what I've read from a few places, it would seem we're looking at a pre-pack administration now. The old company folds, then a new company with what seems to be some similar directors will then purchase the assets via new finance (loans and/or director's funds) and continue operation.
Questionable business practice to some extent, but then by the looks of the park's finances if this didn't happen suppliers would be losing money regardless when the company folded some other way. At least with a pre-pack, existing relationships are still there and suppliers are able to receive money from the park moving forward. The business and popularity of the park away from their ridiculously unlucky three-way issues of flood, rapids incident and COVID are probably incredibly solid, so getting rid of debt now, however unfortunate that may be on creditors is the best way of continuing the park's operation.
I would imagine once/if this happens we'll be saying goodbye to what's left of the thrill side of things at the park. It's clear that's been hobbling along for some time now, and with a declining portfolio on that side of things, now is probably the best time for them to push the family side of things further and concentrate on that at least for the time being.
