Received my 7 day park hopper tickets today - Reading the info on the back of the tickets it states 'Ticket and ID required for entry'! What sort of ID are they after - Passports or Cr Card ?? Would we only require ID for our first usage of the tickets or will we need it for all future park visits?? I don't believe we have ever had to do this in past visits - is this a new idea? There is also a strip on the back to be signed for identification purposes - I presume you dont have to wait till arriving at the park to sign in front of a CM - Any ideas??
