I've just done the Pick-A-Pearl station today. I read a bunch of these comments here, and was able to find a Cinderella Carriage cage for about $10 on
Amazon, just before a went. I bought with my gift card from Christmas too, so it was technically free! I followed the advice saying that the ugliest oyster gets the best pearls too, and I got a blue pearl! The rarest! It will really look like Cinderella's dress in the carriage!!! Thank you all for the great advice!!!
