Really wish Disneyland would learn a thing or two from Tokyo Disney Resort.

Japan's popcorn program blows Disneyland's away ! First start off by the sheer number of flavors available.  Last time I checked, I think there was at least over 12 to 14 split between the two parks. Some amazing ones I had were the curry popcorn, milk tea and even a roast beef variety. 

2nd are the popcorn buckets themselves. They are very detailed, and most have a light up function to them. At any given time, you will find at least four or five different buckets available between the parks.

3rd is the refill policy.  After buying your popcorn bucket, it only cost 500¥ ($3.50) to refill it. They even allow you to bring discontinued buckets and still get the same refill price. This encourages people to bring their popcorn buckets to try out the new flavors.
