I had heard some of the rooms at Royal Pacific were renovated, I think its based on which tower your in.
My experience with Universal Deluxe's after 4 times, (and having stayed in all 3) is that you will get your room later. Earliest we ever got a room was 3:30. (and that was when i went up there and asked them if it was ready) 2 times we got messaged at 4 on the dot. The other time the room was late, AND we didnt get the room we paid for (they changed it from King to 2 Queen and worse view, and didnt give us anything to comp it that was Royal Pacific and it left a bad taste in my mouth). To be fair we always checked in on a weekend day, I could imagine a weekday check in would change that experience.
Meanwhile the half dozen times i've stayed at a value or moderate, they had the room ready immediately. Check in was between 11 to 12 for those, and i was pleasantly surprised. It should be pretty uncontroversial that the higher capacity hotel is more likely to have a room immediately ready and available for you.
