I agree with Koyu, the Adventurers' Guilds are very busy with crafters and the like. There are some awesome spots in the low-level sections of all three starting areas that could be used, such as little villages or outposts.  Another option would be to pick a more out-of-the-way spot in one of the cities.
With a designated "hot spot", one could wander in IC at any time and just check out who's there and what not, as opposed to just drifting through the world hoping to bump into someone.
