Sorry you've been hit by the lost progress, but glad you've been able to keep up.
Do we know what the Costumes will cost, or what effect, if any, they will have on the event? I've just got a feeling that one of the costumes is gonna end up costing gems.
Other than the Zootopia Race Track and Toy Alien, I've got all the characters and attractions. Mickeys Tuxedo, is the only exception. I refuse to pay 120 gems for a costume that doesn't offer any advantage that I can think of. Now if it allowed for collecting the toughest items during an event at a relatively shorter time period I'd atleast have to think about it.
