I was at WDW in April and there was only XXS Anna & Elsa dresses. There was very little Frozen merchandise to be had. You didn't mention when your trip was, but I wouldn't count on finding anything at WDW. Maybe someone who has been there more recently will chime in. More and more Frozen merchandise, dresses too, are hitting the local Disney stores and on line. Look there....every day. P.S. there are a lot of threads about A&E dresses on this board. I recall someone saying Chasing Fireflies has their version of the Elsa dress. It's very pretty. Many other stores like Party City are taking pre-orders.
