I don't ride all
that many rides at any amusement or theme park. I mean I do depending on the park itself but by in large I'm usually limited in what attractions I do either for my motion sickness or too high of drops plus with my husband being so tall there are attractions here and there that I could ride but he would not (though we have some fun times like at Flight of the Hippogriff at Universal when he can technically ride but er not as well as short me

).
We pay the admission fee with knowing that. It is what it is. It's been this way my whole life although I can say I was a tad bit more adventurous when I was 18 at my regional park in attractions. This goes for Six Flags, this goes for my own regional park, this goes for WDW and DL, this goes for USO, this goes for TDL (Tokyo
Disneyland), this goes for Silver Dollar City (albeit that's not the best example as the park has a split ride/experience set up), etc. I can appreciate the sentiment but also understand that it's not realistic for most parks to offer a non-rider a pass with substantial savings. That is making the categorization that a park is solely for rides and while that might be for some it isn't the way the park is set up.
What I will say is that Tokyo Disneyland for example does offer a park ticket for after 5pm (with a closing time of 9pm) for during the week and an after 3pm (with a closing time of 9pm) for during the weekend. The savings aren't super substantial and it's not intended in the least for non-riders specifically but I did appreciate that option. We used the weeknight pass at Tokyo Disneyland allowing us time in the park (but not really any of their get ahead of the line passes were available then) to ride a handful of rides and see the fireworks show instead of doing 2 full days at Disneyland we were able to do 1 full day and the weeknight pass. Then we did 2 full days at Disneysea. The caveat there at Tokyo is the churro, popcorn and parade game is more fierce than you've ever seen in the U.S. They do not have APs right now, they do not have park to park tickets, they do not have multi-day tickets either right now and yet people will pay that full day's price to go in and sit for 5-6+ hours for a parade, the popcorn lines were the longest lines in the parks lol. The other caveat is that Tokyo isn't owned nor operated by Disney company, the owners just lease via a license for Disney.
I think you're going to lose support when you frame it like non-riders ticket or food/drink ticket rather than maybe thinking about it like a timeframe ticket (which exists already for convention tickets often or for specific ticket offers Disney already supplies). What I would expand on Tokyo's system is not having the restrictions that Disney places on. Their weeknight and weekend ticket offers for Tokyo are available to anyone and only have the entry time limitation. It's not tied to a specific locked in ticket offer allowing for flexibility like we did where we just got it for 1 night.
