I know nothing about Toyfair, but I can tell you that fighting your way through TRU can be pure ****. Shop early, and don't count on your local TRU to carry the line, the whole line, or more than one or two whatever it is you are looking for. And, as any parent of a preschooler knows, the scene at TRU on a weekend can put anyone into therapy. Not saying it will be impossible to find what you are looking for there (you may get really lucky and have no trouble whatsoever), but I wouldn't count on it as a sure bet!
