Having read through the plans, there are delays with building the full hotel for a few reasons (I'm guessing mainly money).
The Snoozebox is due to open Spring next year, much quicker they could ever dream of opening a hotel (and much cheaper if it fails), its due to be open for 3 years (close when new main hotel opens) and will have no effect on the coaster developments.
If you think Runnymede denying this would be in anyway shape or form good for the park your crazy, that would set them back yonks and damage potential future investments.
