When I was a PPL holder I transited WLM many times, both via the coastal and inland routes. I never had any problems obtaining a clearance.
Along a similar line, when I was instructing MANY of my trainees used the VFR routes, particularly coastal, both during the latter stages of nav training (circa 50hrs experience) and once fully licenced. All seemed to have little difficulty dealing with it, both during training (and afterwards, based on feedback).
It's just not that hard!
If you ask me what I think of how IFR's are treated by WLM ATC, that's another story!
