Zone Transitions

How is the world map designed? Is it seamless within the Alliance and a Loading screen to get into Cryodiil? Are zones made up like a maze with limited entry/exit points to make the world seem bigger than it is? Are there multiple gated entrances from your alliance into Cryodiil or do you jump in anywhere from the map using the game menu?

I dont want to get into alliance area restrictions here, But I would like to know if the world we do get to explore feels open and contiguous. Or if it will have that labyrinth feeling with little bits all carved up into a game lobby feeling.

edit: removed some extra "a"s

It will be open and have very small invisible loading screens within it. You will zone through it likely without even knowing that you have. This way it seems like it is seamless. Also the world is likely to be open and have little paths from the looks of it in the introduction video.
