Based on the web site a king bed suite is an 825 sq ft standard junior suite.

A king bed studio suite is 700 sq ft premiumsuite costing $50 more on Jan 2. It looks like a junior suite in the picture.

From the description, harder to see why a 700sq ft junior suite is more expensive than the 825 sq ft.

But I assume the issue is who is designating things as standard suites; once labeled premium, I would expect no Globalist upgrade to that suite by a front line reception desk employee.
