I think what people are losing sight of here, is that different people have different budgets, preferences, and vacation preferences. Universal will soon have inventory for all types of guests.
If I'm going with just my wife in the offseason and parks close early, maybe Sapphire and the like would be more ideal. i.e., we're spending more time at the resort.
If we're bro'ing down and doing late HHN nights, Aventura and Dry n' Tame look like bigly values.
At less than $100, these hotels are very attractive. You know you're getting quality with Universal/Lowes. It's a sure thing which I-Drive, Air BnB, etc cannot guarantee, and you don't have to pay for Uber, etc. This also could just be a place to sleep the night before you move to a nicer resort.
The only thing Universal is missing now is its own version of Magical Express.
