Am I reading these numbers correct? DLR has 77 attractions between two parks and WDW has only 85 attractions between 4 parks? I see why more and more people go to DLR.
You are reading them correctly. It's been a topic here before, but the numbers speak for themselves.
There are some exclusives for WDW though. EPCOT is the huge example of that, with 23 "Attractions" but only 8 of them actual "Rides". Each World Showcase pavilion counts as at least one Attraction, even if it's just a pretty themed courtyard of shops and a restaurant, like Italy, Germany, Japan, Morocco, etc.
But just to give you an idea of the differences, here's the list of E Tickets in each park...
Disneyland - 11 E Tickets = Jungle Cruise, Indiana Jones Adventure, Pirates of the Caribbean, Haunted Mansion, Splash Mountain, Big Thunder Mountain Railroad, It's A Small World, Matterhorn Bobsleds, Space Mountain, Finding Nemo Submarine Voyage, Star Tours
DCA - 5 E Tickets = Soarin' Over California, Grizzly River Run, California Screamin', Tower of Terror, Radiator Springs Racers
Magic Kingdom Park - 7 E Tickets = Jungle Cruise, Pirates of the Caribbean, Haunted Mansion, Splash Mountain, Big Thunder Mountain Railroad, It's A Small World, Space Mountain
EPCOT - 4 E Tickets = Spaceship Earth, Mission Space, Test Track, Soarin'
Disney's Hollywood Studios - 3 E Tickets = Tower of Terror, Rock N' Roller Coaster, Star Tours
Disney's Animal Kingdom - 4 E Tickets = Kilimanjaro Safari, Dinosaur, Kali River Rapids, Expedition Everest
One could argue over whether badly aging but physically long rides like Ellen's Energy Adventure or The Great Movie Ride or Listen To The Land or Gran Fiesta Tour are E Tickets or not. That's what makes us Disney nerds. But the overall ride count still stands, and it quite clearly should have been a giant red warning bell to anyone planning on implementing MagicBands and FP+ in theme parks that don't have enough rides.
