There was not a single Falcon-sized tunnel to the Main Reactor. The vast majority of the Death Star was unfinished superstructure, meaning much of it was mostly empty space between scaffolding and lattice. There were
many
routes to the Core, all of which just required flying through the scaffolding, not one single "weakness tunnel." Which is why Wedge is "path-finding" for the attack run, rather than just following a one-lane road ("Lock onto the largest power source... that
should
be the main reactor..."). It's also why half of the attack group could just break off and fly back toward the surface ("... and see if you can get some of those fighters to follow you."). Basically, it would be like trying to fly an RC Plane through the skeleton of a skyscraper that's being built, before they install all the walls and windows and floors and ceilings. You'll see a lot of bundles of wires and pipes and girders (same stuff we see inside the DSII), but there's a lot of empty space to find a route through all the junk. But it is very much NOT akin to, for instance, flying an RC plane through the airduct highway of a finished skyscraper.
Fun fact: there were also originally scripted to be scenes where Jerjerrod is ordering his crew to shut down sections of the Death Star and to power up other areas and flood sections with radiation and stuff... he was effectively trying to mess up the sensors of the Rebel craft and get them to wander through the superstructure chasing phantom signals rather than the actual core.
