It took us each about 20 minutes. It is not a long or complicated process .Hi! How long does the droid building experience take? I just booked it at 6:10 for my two kids, DS15 and DD13 and Im wondering if we have time afterwards to hit Ogas for a drink before the 9pm Fantasmic which we will have had 4:20 BB Dining package for earlier. Not sure how early we need to be at F! for Dining package reserved area seating and dont want to rush anything. We can hit Ogas another night/day during our trip too if the time would be too tight.
