I'll admit that the homeless is part of the reason I always pony up and stay on site (or drive and pay parking and fight traffic and stuff). I'm a little surprised Disney hasn't flexed it's influence and pushed the bubble out a couple blocks/streets deep around it and made sure it was clear of homeless in these areas. That area probably is better than a lot of places, but I still don't want to be walking by homeless people at midnight or 1am (well, I guess the parks close earlier now, but pre-covid I often didn't get back to my onsite hotel until midnight or maybe even 1am if I ducked into DTD shops). This is especially true if I'm solo or have a lady with me, it's just not something I want to experience when I'm paying so much for getting down there and the day in the parks and honestly the price difference between the onsite and offsite hotels is sometimes only like $150 or $200/night. I get that the difference is a huge amount, but at the same time for shorter walk and NOT having to deal with maybe a drunk or mentally unstable homeless person to me that's well worth while.
I'm not sure about the homeless outside of the US, but my experience here is that they often have mental issues or are often on drugs. That kind of stuff worries me. While I don't enjoy walking by someone down on their luck and living on the street, I'm on edge if I walk by someone that I can actively see is talking to himself, yelling at others (people that aren't actually there), or clearly is still under the effects of drugs. Seattle is getting bad in areas and Portland absolutely looks like trash in spots, I've basically avoided Portland since the start of the pandemic and likely will until they clean up their streets.
I can totally understand the worry for a solo female, small group of women, or anyone with kids. The city should work hard to address this problem, but short of that, they should also work hard to keep that area empty and very safe feeling. Disney is a cash cow for them, it brings in a lot of people that are paying hotel room tax, renting cars, purchasing items, and dumping money into Disney. I highly doubt Anaheim would have even a 10th of the visitors they normally do if Disney wasn't there....
