At the same time, if paid front-of-the-line access is coming to the US Disney parks (and there's good reasons to believe it is), then everyone can purchase it and this benefit will be much less exclusive and special. On top of that, it will be much easier to place a cash value on it, which I suspect will be 25-30 USD for something like Rise of the Resistance, so you can sort of parse out the actual value of the benefit instead of having it be buried in the total hotel cost.
Unless, of course, they further differentiate Galactic Star Cruiser by offering front-of-the-line access to the paid front-of-the-line queue, which is some Inception-level 4D chess that I wouldn't be terribly surprised to see from Disney. Private tours already have that benefit, or so I've been told.
