I having been waiting for later times to open. I tried at the 30 day mark for the 50s PT for May 1 and nothing. Not until I got 3 weeks before (to the day) did they open the later dates. I asked about my PS for May 3 and nothing later. So it's looking like 3 weeks before, not 30 days. I've since gone through my list and marked each day at the 3 week mark and will call when a couple of them past that timeframe. I was also trying to get a little later PS at the Plaza...right now the latest during EMH evening is 4:50PM. While I'm sure MGM dining will open for later times, the Plaza is notorius for closing early no matter what the park hours are. Tomorrow on the 16th I will call again for my May 8th times. So presently I'm now holding a 7:30PM PS at the 50s PT for May 1, but so far, it's the only late time that has openned for my trip in 2 weeks.
