If the development of Wild Place continues apace, then I think it really will challenge Noah’s Ark for local hegemony.
I hope so and let's not forget the trump card for Bristol/Wild Place -they're open on a Sunday (Noah's Ark isn't), so if someone wants a zoo near Bristol on probably (?) the second busiest day of the week then Bristol/Wild Place are the only games in town.
No, you are correct. Noah’s Ark doesn’t - yet - match the visitor numbers at Bristol. They, apparently, receive about 200,000 visitors per year (and rising).
So, contrary to what I wrote earlier, the zoo continues to enjoy a Bristolian hegemony- although their position is certainly weakened by the presence of Noah’s Ark - particularly as the latter place makes much of advertising itself as being a zoo at which one can see “big” animals.
I think that's partly down to the "gifting" of Noah's not being open Sunday and Bristol does seem very popular (ideal ?) for families with with very small children. I've never seen a zoo with such a high proportion of young families/toddlers/infants -that said I've never been to Drusillas.
