To camp straight from character to character without stopping at the character select screen, create an in-game macro for each character you want to switch to, containing the following lines:
Replace <Character Name> with the name of the character you want to switch to. You will camp directly to that character without going to character select.
If you're into custom UI's like me, you can go to the eq2interface site and download Pooka's FastSwitch Shutdown mod. When you select Camp from the EQ2 menu it brings up your list of characters (you have to edit the XML, but there's excellent instructions with the mod on how to do so), and you click on the character you wish to and it camps your character and logs on the next character without even going to the character select screen. You can set it up for 6, 10, and 12 characters. I highly recommend.
