There's no price difference in the actual room rate.
The important points are the change and cancellation policies. The package policies are quite restrictive. With a room-only reservation the worst that could happen is you'd lose your one night's deposit. With the package reservation, you could conceivably lose the entire cost of the package if you canceled the day before arrival, and you'd lose the $200 deposit if you canceled between days 29 and 2 days before arrival.
I'm not sure why you--or anyone, really--would need a package. You can purchase tickets separately with ease, often at a discount through an authorized vendor like
Undercover Tourist. The packages throw you a mini golf voucher, which is something you might not even use or want to use.
The only time I ever booked a package was several years ago when WDW had packages for a 7-night trip but you paid for only 4 nights. It was well worth it. But I haven't seen anything like that in years.
