You can always check when you get on board if there are any additional openings or if they have had cancellations.
By shopping there, if you mean buying the dresses and shoes.................I would think that would be something you could do. I think I would shop for that stuff prior to getting on board as we have found better quality items at a good price buying online and in stores. I think there are numerous etsy sellers producing high quality princess dresses. Just my opinion.
