Oh yes, traveling from one event to the next sounds really like a good plan :-))

Usually the press card gives you free access, so it replaces a regular ticket. Yet, most of the time you need to register/apply first and then the event organizers confirm your participation - or not (since the no. of participants is always limited).

Obviously, the bigger the media's name you're representing, the higher the chances to get on the list :-)

With my upcoming trip to Bali in mind, I've contacted the WSL (World Surf League) now in order to know if I need to officially register before the championships, or if I can just pass with my press card + ID in hands. Let's see what they reply :-)
