This is a helpful thread, thanks.
Looking at doing a premium redemption. Sky's premium is the same size (30sqm) as regular, Olumpia is 40-50sqm vs. 21 to 30.
Given that Olumpia is less points (42k vs. 57k at Sky for premium redemption), I'm leaning that way unless the Olumpia big room is clearly not as nice as the Sky's big room.
Anyone have further comments on the premium redemption choices?
