Google "Project 99 Hunting Guide" on google docs, it's really handy, multiple good places to xp for every level.

Another similar guide (which incorporates just about every spot in that one, plus a bunch of spots from other guides) can be found here:

http://wiki.project1999.com/Per-Level_Hunting_Guide

However, it's a more soloing-focused guide, so while it has plenty of spots for grouping the guide won't tell you which ones are popular nowadays.
