Yes, I always make ADRs for resturaunts I want. An experience I had the other night made me think it was definitely the right thing to do. I'm going solo in September and wanted to eat at Coral Reef. Five months ahead, 5:40 was the latest I could get on either of 2 nights. When I said, "Wow! That's the latest you can dine at the Coral Reef", the CM emphasized, "Well, for YOUR party size!", implying there were larger tables available later, but not for solos. It was the first time I'd experienced having a harder time getting ADRs for one than for a big party.
