I haven't been to WDW in several years, but I have never had issues getting the ADRs I want. Today I was ready and waiting with windows open to search for three popular options: 'Ohana, Chef Mickey and Crystal Palace. I ONLY got Crystal Palace. There was no availability for CM and Ohana for ANY of the days during my trip. I have set alerts through a subscription service, which came through for me earlier this year at DL, but I am floored. REALLY? No availability? And I was fast and efficient!
