Yeah, but at Universal, you get to get in whatever express lane you want, all day, without a return time. I actually went to MK with G+ on a Saturday then USO the next day. At MK I skipped Jungle, Pirates, Carpets, Big Thunder, Mansion, Pan, Mermaid, Pooh, Tea cups, Space, Buzz. (rode other things, but this is what I used G+ on)
At USO I had significantly less of a wait on Forbidden Journey (x3), Hippogriff, Hogwarts express, River adventure, Kong, Hulk, Spiderman, Cat in the hat, Seuss Trolley, Gringotts, Men in black, Simpsons, ET, and Despicable me. We also rode Hagrid's that day without the skip
Why should there be an extra perk for deluxe guests? The hotels are filling up right now. The hotel, location, transportation seems to be enough. Especially with DVC being included in deluxe and them already being locked in for 50 years not matter the perks.
