I'm going on my first ever trip to Whipsnade on Wednesday, so I'm hoping that most of the animals will be out then, though I'll probably be a bit early wolverine wise by the sound of it.
Be warned- Whipsnade is very weather dependant because its on top of the Downs. On a good day it is great, on a wet or windy one it can be pretty miserable. These new developments are on the more exposed side of the park too.
