connecting rooms

Which deck plan map is right?? We just booked a Disney cruise through Costco and on Costco’s website, the rooms we booked (2020 and 2018 on the Magic) are connecting, but on Disney’s website, they are not. Of course asking these two entities about it they say exactly what their map shows them...

For those of you who have tried for getting connecting rooms at the Poly using points, how many were successful? We are considering adding on some points here because we like the resort but have a family of 5 and enjoy the 1 bedroom/2 bedroom (affordable point) options of the other resorts...
