I can confirm driving there is a complete mess in the afternoons. We ended up parking across the street at the Cast(?) parking lot. A little further walk then normal. Waiting for the crossing light to walk across was 5 min one time. It took an extra 10-15 min to get through traffic and park and maybe an extra 10 minutes to walk/wait for crossing light. It was SUPER crowded, but we are used to crowds at WDW in the summer. Give yourself an extra 30 minutes for parking and anticipate it be crowded and you'll be okay. Make dinner reservation before or as soon as you get there and walk around for an hour or more.
