How much is a Disney+ account, and how many people can share it? And are they fussy about location?

For a while, I had a seat on a YouTubeTV account with my nephew (which allows up to five or six people), but he's in Chicago and had to keep signing in for me every couple of weeks, because otherwise it would lock me out for being in Minneapolis. Apparently the sharing is really intended for family.

But if Disney+ isn't so annoying, I might be interested.
