Guild Wars 2

well i just got the game and i only have basic knowledge from my friend but i think i get what people are saying. Would it be recommended to check around midnight to try to get into Crystal Desert?

so there is no chance that i could enter a full world due to the fact that it has the maximum amount of accounts tied to it?

uhm i thought that once you create a character in a world it becomes permanently stuck there.

So i wanted to play GW with my buddy on the world he is in but it is always full. How can i get into it without it being full besides waiting until late night or if i do manage to get in will the population of the world affect my ability to play the game when i want too?
