To compare, a family of four could spend five days at the Universal Orlando Resort with a suite and Express Pass for $2,000 cheaper than a two night stay at the Star Wars: Galactic Starcruiser. 

Even staying at The Grand Floridian Resort (for five days) is cheaper.

Disney has recently offered Disney Vacation Club and multi-day discounts to encourage sales.

The Star Wars: Galactic Starcruiser is built like a cruise ship on land. All entertainment, food, and non-alcoholic drinks are included.

This does help warrant some of the cost.

With a new experience happening every two days, perhaps Disney has sold to most of their richer visitors.

The target demographic for this experience is much smaller than Disney's usual customers.
