There is no way I would stay at Universal if they didn't have express and early entry. I haven't stayed at a deluxe in 15+ years because even the express isn't worth the upchage to me. If I was rich, Universal's resorts are some of my favorites, ahead of most Disney resorts. Havning everything right there and the night walking paths and boats is my favorite immersive theme park experience. Just can't justify it when I can spent 1/4 the amount on lodging and just deal with the lines. If I DID splurge for Universal hotel and they took those perks away but kept all my money I'd be mad.
I really see no reason they can't do both. Especially early entry. For express, just calculate how many people will be using them per hour and take that out of the virtual queue reservation system. Flash your express and get in line with people returning with their VQ reservation. If the line backs up you might be told to wait to the side for a few minutes before the line goes down. The reason Universal is able to offer express to everyone in the deluxe hotels is because it is so few people that it does not back up the lines the way Disney's FP system does.
