As far as distance, I just worked all the options up in Google Maps.
From the front entrance of Beach Club to the Norway pavilion - 0.7 miles
From the International Gateway to the Norway pavilion - 0.5 miles
From the Monorail exit to the Norway pavilion - 0.5 miles
So it's a closer walk from the monorail, but a wash from the IG. Since you are coming from the Poly, I'd just take the monorail. I'm not exactly sure why you are planning to use an Uber in any case.
And out of curiosity, from the International Gateway to the Norway pavilion proceeding counterclockwise (to the right at the IG) - 0.7 miles.
