Since it was discussed earlier in the thread: Stardust Racers does seem to duel as mentioned later in the morning. The green track appears to be having some issues (or at least during my visit Wednesday) because only 2 trains were running with guests and the third had ride technicians getting on and looking at that particular train and ran empty otherwise.
There’s also additional signage asking guests to keep their shoes on do the ride with an audio announcement stating the same, and that losing a shoe on the ride can cause ride delays.
In other news, Blue Dragon is delicious with excellent service as ambiance and Oak & Star had a live band playing on the little stage in the corner. Live music was prevalent around Celestial Park which was nice to see.
