It depends on how much time I can come online and whether I have no projects to work on through the week. However, knowing the call of the muse, I sneak online when I should be working. My places vary very much. I never stay in one place for too long unless I decide to hang in a particular spot for a while.
I don't have a time, day, or even get off time when I hop online. I can't make solid times and days I get online, but here are a few places I tend to park myself.
In Bonfire, anywhere being from near the portal or by the water.
I can some of anywhere in the Plains. Even hot spots, like stone bridge or near the portal.
In South Pole, like the Plains, I can be some of anywhere or by the portal.
In the Cape, Last Cave, or Altantis, I will often stay in one place for about thirty minutes and trot some place else.
