I feel like its tricky to find fault with Whipsnade's enclosures, but there seem to be a few instances where the size and quality of some of the hoofstock stables hold the modern zoo back from housing the large herds of rhino and antelope it did in the past. I'd also concur that if serval and vultures were to return - which I very much feel they should - Whipsnade of all zoos surely has the space to house them in a purpose built enclosure on the site.
