well it definitely now sounds like they are, based on the new brochure.
I'm still going to call to be on the safe side, but I actually just went through a couple of the menus for the ADR's we have and found a few that based off of the lunch prices and what they offer, we wouldn't have gotten our dollar's worth if we used TS anyway (Sci Fi and Whispering Canyon, to us, have skippable entrees and very sharable desserts). It would be pretty much a waste for us to use TS credits at those.
So IMHO, if the split credits do end up being a fact, my personal suggestion for people would be to preruse the menus before you go, and look to see if you have ADR's where the adult entrees are mostly in the $10-$15 range. These would be mostly lunch menus at non-buffet/family style places. Pay OOP for those and save the TS points for your 2 pointers, or for dinners only, which tend to be a lot more expensive.
