Rollercoasters are cheap, slow loads meaning huge queues, and are aimed at a specific thrill seeking audience rather than the whole family.
It's getting tiresome the sheer volume being built lately. Sea World, Six Flags make alot of coasters as they are pretty cheap to make. Disney shouldn't be looking at budget attractions not at a time of record attendance.
I'm not a major coaster fan either. I don't do Six Flags, Bush Garden/Sea World coasters ... but to be fair, Guardians coaster hardly sounds like it's going to be 'cheap', though I understand the point you're making. They're "easy thrills" and folks run to them and love them. I'm not super fond of RnRC because I thought it was a lazy attempt to counter Islands of Adventure at the time. I still don't care much for it but man will people defend the Aerosmith theme, lol. So ....
Disney is balancing it at least with dark rides. We just got a boat ride (with one in the pipeline, maybe/possibly). Yeah, they have screens but it's not sitting on a non-moving (non-moving meaning you are seated and not in a moving vehicle that moves around show scenes) seat that parks you in front of a screen the entire attraction. So it seems balanced to me. The parks probably needed a few more coasters to appeal to that crowd, whether I like them or not I know there's a huge audience for them.
Let's see
- Little Mermaid (omnimover dark ride)
- Seven Dwarfs Mine Train (family coaster - replaced dark ride)
- Flight of Passage (simulator, on bikes, and better than Soarin')
- Na'vi River Journey (slow moving boat ride)
- Slinky Dog Dash (family coaster that DHS needed; though I'd rather have Monsters this looks fun enough, bare steel aside)
- Alien Swirling Saucers (flat/whip ride)
- Mickey & Minnie's Runaway Railway (LPS dark ride - replacement)
- Star Wars Battle Escape attraction (LPS dark ride)
- Star Wars Millenium Falcon attraction (simulator)
- Ratatouille Kitchen Calamity (LPS dark ride)
- TRON Light Cycle Power Run (bike coaster)
- Guardians of the Galaxy attraction ("drifting" coaster)
I'd say there's quite a variety of attractions. But compared to the past it does seem, in isolation, that a "lot" of coasters are on the way because we're not used to them adding them, but I'd say they needed to fill a bit of a void. And they have a slew of LPS dark rides coming. Not to mention the possible Poppins dark ride.
We also go from no LPS attractions to three, two in the same park.
