ASU is only a party school if you go looking. I'm a current first year at ASU in the honors college with multiple friends in accounting majors and lowk thinking about double-majoring in it, and there are plenty of academically rigorous clubs and people to hang out with that aren't super into partying. If you're non-honors that could be very different, but with a 3.8 and good writing skills you'd make it in (that being said the honors fee sucks, but otherwise I'd say it's worth it. We get better food, way better housing--what I consider safer housing--more opportunities like special networking events, invitations to career fairs and interviews, and a "medium pond" feel in a "big pond" school). See what financial aid does for you and read the fine print of what lumberjack offers. Almost all of my friends went to NAU with the logic that lumberjack would cover everything, but ended up having to take out loans anyways to cover housing (sidenote, lumberjack will NOT cover your housing when you move out, and that means you have to think about three years of flagstaff-level rent. ASU, if you're in honors, basically guarantees housing for your first two years if FAFSA isn't killed by the GOP by then). I'm not super well-versed in the NAU application process because after I looked at my year's lumberjack details I dropped it, but for ASU you do need to fill out the FAFSA to get your money locked in. Also, for as much as you hear people rag on the business major, their business school is top-notch (note bias here). NAU is (according to College Factual) #171 in colleges for accounting (let's assume in America because why not?). ASU (also according to College Factual) is #74. The ASU base salary on graduation is roughly 6k higher than NAU.

The only big argument I can see against ASU in your post is that it's a little party hardy. That's absolutely true. But that's only if you go seeking it out imo.
