You could try to hold out for a sale on the Crocs website... They just did a 2 for $20 sale a few weeks ago and I got 6 pair of crocs for $59.94 and it should have been $193!!
I wanna say the Disney ones were $39.95 at the parks. They were $34.95 at the outlet(regular price) so I would say they were worth it. I don't remember how much regular ones were at the parks, but at the Crocs store, they were $29.95.
