As a person born and raised in Maryland I think there are 2 big problems with the crabcakes at WDW.
1) No Old Bay!
2) They don't use Blue Crabs.
I had the crabcake at Flying Fish and while it tasted reasonably good as food it wasn't a real Maryland Crabcake. I'm not sure what type of crab they used but I suspect it was dungeness. But in it's defense it didn't say Maryland Crabcake on the menu.
E.T.A.
I checked the menu and the Flying Fish is a Peeky Toe crab which is a Rock Crab not lump Blue Crab. There's a big difference.
I couldn't agree more. I kept reading it was the Old Bay (which is a staple in our neck of the woods), but if you don't have the Blue Crabs, you don't have a Maryland style crab cake. It's that simple.
Having said that, I do make a pretty mean crab cake using Heaven forbid, pasteurized crab from who knows where. They're always selling it, buy one get one free at our grocery stores. It's claw meat and fairly cheap, but it does in a pinch.
To the OP, while you won't have the best crab cake money can buy in central Florida, IMO, you can get a feel for them by trying one there. Especially when you're in Canada and probably don't have much access to the Blue Crab. I concur with those who suggest you definitely get it broiled rather than fried, though. Just keep in mind, while whoever is picking the crab tries their hardest, there are times when you get a shell in your crab cake. It just goes with the territory. I think when the crab cakes are fried, it must disintegrate this bit of shell because I've never gotten a shell in a fried one in my life (though admit, it's a rarity that I eat them this way).
