There are a ton of Web sites offering info on Orlando -- and coupons. There are a couple outlet malls up there too. I haven't gone to O-town to shop lately [just to visit Disney] so I am not sure how many outlets are still up and running.
There's also a high-end mall -- Millennium maybe? I've never been to it, but my daughter went to college up there and it was her favorite shopping place!
As far as Port Canaveral ... not much in that area, except for Ron John Surf Shop in Cocoa Beach.
