We had no trouble sharing with our DD at the table service places...of course, we also did this at the counter service locations as well.
I believe the places (TS) we shared were Le Cellier, Rose and Crown, Captain Jack's, and 50's Prime Time Cafe. There was always more than enough food to fill us up...actually, I don't think we ever left a place without food leftover on the plates!
We actually did end up with an "extra" meal this way. We didn't plan it that way, so we didn't have an ADR...that is how we ended up trying Capt n' Jacks (they don't take ADR's). It worked out very well...the food was excellent!
