The Galactic Nights are so far averaging one a year -- not one's usual definition of a 'cash grab'.
In place of SW Weekends, Disney has provided for free:
- Upgrades to Star Tours and Jedi Academy
- new SW museum, short films, and M&Gs
- 2 new Stage Shows
- A brand new fireworks show (projections added later)
And all this every single day of the year. For free. And they're building SW fans two new E-Ticket rides and a fully immersive land. For free (of course, we all understand 'for free' means 'with no upcharge'... we're all paying a park entrance fee).
And "for free" you get: expansion of DAK ride hours; RoL; ToLA; night time shows; and Pandora.
And "for free" you'll get TSL.
So, yes, there are premium things you can buy. For example, a plush Mickey for a few bucks. That costs extra! It's an upcharge! So is their $1,000 VIP Tour that's been around forever. There will be more upcharges coming along. Whether it's a souvenir, specialty food, tour, limited ticket party, or priority seating. But there are also billions being spent to give everyone more free stuff. Let the deep pocketed folk fund the park expansions you'll enjoy for free.
