I've just noticed something.
If you look at my one page guide to ticket prices, the Early Bird wording is applied to every age group on weekly tickets (second image on page) but only to the Adults line of the All-In-One (first image on page). It seems to be missing elsewhere too, in other of the images - is this intentional?
I guess you only notice these things when they are all on the one page.....
Also, is there any reason why the Early Bird wording is used against children's tickets when these are free anyway?
exceedingly helpful summary of tickets page
