There seem to be so many but which is the most enormous one?
I not sure the newer stores are the biggest, but Tink mentioned the older one we used to visit--which is ginormous--is seriously in decline. Not in a particularly good area and the store itself is becoming rundown. :sigh;
The one I've been to is on SR535. My touristy directions are: exit DTD on Hotel Boulevard, turn right on SR535 and continue until you reach WalMart on the right. I'm guessing it's two or three miles after you drive under I4 freeway.
Not the largest WalMart SuperCentre I've visited, but certainly contains a lot of merchandise, including a Disney section. It would keep you busy for an hour or more, if you choose.
There's another way to reach it from WDW, but it's harder to explain in my touristy manner.
will be visiting next tue just after we drop off luggage at villa:tongue0011-1::p015:;)
