hi there - dh and i were in disney with our son in january and bought the refillable mugs. we are going again in september - any idea if the design of the mugs will be different? we love buying our new mugs as part of the first things we do when we arrive in disney! the mug designs haven't really changed at all in the last two times we've been and what was once a really fun collection of different mugs is getting a little boring with doubles and triplets of the same mug. any idea if they are going to change up the mug design any time soon? i hope so!
