Noah's Ark is going to be very real competition for the Bristol Zoo's new planned environmental Park.
Bristol Zoo's park will no doubt be far more lavish, far better designed and with attactive enclosures and nice plantings, whereas Noah's Ark is largely at least at present, simple enclosures built on open farmland(am I wrong?)
Bristol's entry price will probably be double(or more) that for Noah's Ark.
But most important, Noah's Ark is already established and they are getting more animals each year. And if they do get elephants, thats another major point they will score over the Zoo.
