Walt Disney World has announced that they will begin taking the first bookings for the Star Wars: Galactic Starcruiser experience sometime later this year. Prices have not been set yet, or at least not made public, but the rumored expectation is that when the 2-Day / 2-Night stay on the Starcruiser begin in 2021, it will be quite costly. Even more so than a trip on the Disney Cruise Line.
They have posted a fun new video explaining more about what you can expect from a voyage on the Star Wars: Galactic Starcruiser, which you can see below.
