No, they eliminated early entry in January BUT they now open Disneyland one hour earlier EVERY day. This is open to all, not just those staying onsite or booked at one of the Good Neighbor hotels.
I was there a few weeks ago in early March, and the official opening time was 9:00. We were able to get in to Main Street as early as 8:30 (not sure what the earliest would have been - maybe 8:00), but the rope didn't drop to allow access to the rest of the park until 9:00.
That would just be one hour earlier than they used to open to the general public. The times posted on their website should be correct, current, and accurate.
Also, one can always enter the park about an hour before that to stroll Main Street and get some morning coffee, muffins, juice, shopping, etc.
