According to the Croc website you should be able to buy them at Orlando Airport, Dilliards (Florida Mall), Journey (Premium Outlets), Stride Rite (Florida Mall) and the Walking Company (Mall at Millenia).
I didn't see them in any shoe shops last July when I was across there but these shops are now listed as stockists.
Anyone in the North East who is after a pair, Peter Barratts Garden Centre at Stockton sells the Beach ones for about £30.
I fancied the Nile pair myself so if anyone sees them over here let me know.
