Wild animals days out - any good deals?

[ladywotlunches]

Hi all

My son is taken by the idea of the Tiger cubs at London Zoo, thought I'd prefer somewhere where there is more room for the animals to roam like Port Lympne. Anyway, the prices for both are well up in the ?70-80 mark for a family of four. Anyone know of anywhere doing 2-4-1 deals or similar for the summer hols?

thanks!
