WMSP have applied for planning permission to Wyre Forest Planning, to develop a range of new animal enclosures, which will include the development of 8 'Holiday Lodges' in-cooperated into the main animal Safari. Plans online at the moment don't showcase anything design wise, more just the proposed locations.
Appears that the previously rumored and pre-planned Hotel & Waterpark has been put heavily on the back foot, and I very much doubt it will be developed after years of decreasing motivation by the previous owners surrounding the project.
I think this proposal of 8 lodges might work quite well, and will ultimately provide a great test to see if there is a market and wider appeal for any sort of accommodation at the park.
