Play WOW from collage dorm?

I’ve been thinking of getting into private servers in order to take a trip down memory lane again, I started playing back in late wrath, but I’m moving back into my college dorm some time next month.

Now here’s the problem, their internet usage has an anti-piracy policy as is to be expected, and I’m afraid they might decide private server usage counts as piracy. Last year my RA told me they don’t even turn on their monitoring unless there’s a lot of heavy usage in a short time frame, but I’m still concerned about this issue.

So I’m wondering if there are any solutions? What would you guys do about it? VPN? Any tips on picking one? Is it really safe?
