It's on the menue at CRT for teh celebration which is 18 months long and ends at the end of next year. No one knows if it will become a permenant or not.You can also order one if you plan on eatting at any of the grand floridian restaurants but you must oder it at least 48 hours in advance , it is $14 and slightly different than the one one at Cindys.... it comes with a silk screen image of the castle and a chocolate teardrop.
I dont know if they are available to go .... you can always try but Cindy's is a very busy place and I also dont think it will hold up very well. You may want to call the restaurant directly.Also as far as I have heard the GF does not allow their slippers to be transported...it has soemthing to do with the mousse inside... you can order it from rooms service I believe... you may be able to pick it up at Gaspirall's ( I thin thats what its called) which is like at food court at the GF so you can sit and eat it there without ordering a meal.
