depending on when you'll be there, you might not need PSs.
We've gone during value seasons where we could just walk up and only wait 10 minutes or less for a table. This september, we only have 2 PSs - one for WCC and one for Ohana. The others we'll just see.
If you don't want to make PSs for lunch, your best bet would be to eat at the off-hours or eat at a resort. Since the majority of people will be at the parks during lunch hour, it stands to reason that the resort restaurants will be less packed.
We practice this for Kona Cafe. We'll be at MK, go out to Poly for lunch at Kona, then back to MK. Didn't have to PS it at all.
If you want to make PSs anyway and let the kids pick, go to allearsnet.com and have them look at the menus. Then they can decide where to go for lunch and you can make your PSs.
