Once, yes.
The Stitch figure itself is actually top-notch, and and the ride adds a neat element in the form of a couple automated laser cannons that aim at the guests.
Plus it's almost always walk-on, or at least walk-in.
You know, thinking about it, does anyone else think the attraction might be a good candidate for a third overlay based on Wreck-it-Ralph?
They could really plus the ride by adding some of the new-generation projection effects used at that execrable Jack Sparrow show at MGM. You could do all kinds of cool things like having the video game characters jump on/off the video screens in the room as the arcade police or whoever tried to isolate the "glitch". Venellope could appear in the central tube at first and after some hijinks be replaced by Turbo/bug.
For added fun they could relocate the arcade from the Space Mountain area to Merchant of Venus so that you exit through an arcade instead of a merch location.
