Thanks for the update and hopefully the latest improvements will get them back on track.
One interesting statistic is, visitor numbers were 450,000 for 2012, whereas Fota and Belfast (good zoos near big cities) each had less than 400,000 visitors. Considering Taytos limited winter opening hours and the remoteness of the site combined with the below par zoo experience, the above figures are a clear indication of the greater visitor appeal of the theme park/fairground type of zoo.
