You'd have to price out all components separately to see exactly what everything costs. It is possible to get a room discount and add on DDP & tickets, making it a package. Or get
free dining.
We booked a room only last January and went without DDP, and saved $. Still ate TS most nights. We ate at the less expensive TS, we don't drink pop, so water is fine, shared a dinner dessert, and didn't have desserts with lunch. It was just 20 something daughter & me.
We shared 1 or 2 lunches- the pasta at POR food court is Huge, and so are the SciFi sandwiches.
I took about what we would have paid for DDP, and put it on a WDW gift card, and used that for dining. It was just like having the DDP, just show a different card
