Just to add, you could also boat to CR (in the afternoon), then monorail to Poly or GF. Of course, also a very quick Uber or Lyft ride to any of those as well.
I do think it would be nice if Artist Point was more like Topolinos, with a non-buffet character breakfast in the morning and a nicer, table service in the evening. But, it was super easy for us to head over to CR for dinner at Steakhouse 71 while we were there using the boat. And the Lyft ride to Coronado for dinner another evening was less than 10 minutes (and less than $10 before tip, as I recall).
