It really depends which entrance you want to go into. The old pedestrian entrance off of Harbor is still there, and all of the hotels along Harbor (between Katella and Ball) are just steps away. Though, they used to have big troubles with tourists bolting across Harbor to get to DL so they put a fence up along the whole stretch of Harbor along the center median, so even if you are technically closest to the entrance, you still have to walk to Harbor and Katella to safely cross the street at the crosswalk.

You can also enter on foot through Downtown Disney, and that technically would put all of the Disney hotels as the closest, but there are also a slew of hotels along Katella as well near Disneyland Drive (some maps may still call it West Street) that would be closest to enter on that end.

Also, not many people know this, but at the far end of the Timon parking lot, there is a little gate for pedestrians. You can enter into that gate, walk across the parking lot, and just hop on the Timon tram and ride to the main gate.
