Yeah... WDW beats DLR hands-down. But just comparing Magic Kingdoms...
INSIDE-FACING DLR... Man, I hate the forward-facing cars in Orlando! Makes it feel like transportation, rather than an attraction unto itself. Plus, no Primeval World.
NOS... If you're not going to build WRE, Orlando, you really should have built your own NOS, and since HM was in Liberty Square, you could have come up with a brand new, unique, kickin' Mardi Gras ride or SOMEthing. They had the space, they just didn't use it well enough.
Splash... don't care either way about side-by-side seating. What I didn't like was that their Splash was a bit TOO bright. It felt like the rockwork wasn't complete in sections, and you were just seeing bare black wall between scenes. Maybe I was just there during a rolling refurb or something.
TSI... didn't like the layout of their island. Like I was saying elsewhere, there's a bridge to the back part of the island, and if someone's coming from the other side, you can't cross. Or you have to throw up your elbow and rush it.
Fantasyland... bad iasw. And what's with the Sad Clown??? No Storybookland, and no matter what some people think, that is a criticism not a compliment.
Over all, even on my first visit way back in 88, I just felt like Ortlando got short changed, but at least they had Epcot Center. Of course, poor Horizons bit the big one, which pulled the heart out of Future World. But in its plus column, it is more spacious, and as a result, they've been able to keep more of the classics like Country Bears, the REAL Treehouse, and the PeopleMover. I go to that park more to see what should still be at Disneyland than for any other reason.
