How sweet! Disney is gorgeous and has a great cage set up there!
I found that they loved tunnelling, burrowing, climbing and their wheel! Loo roll tubes are great, they love to attack them :P
You could also try putting some of them under the wood shavings to make an underground tunnel, i used to make some holes in them before i put them under though to allow some air in. I used one of the mazes before and they would climb all over it, the more complex and interesting the better.
Oh and also one of the wooden log with the holes in them, they like them too and mine would even claw at it, great for trimming nails!
