Actually, there was a lot to do at WDW in 1988 that doesn't exist today, or is not kept up as well. No, we didn't have the Animal Kingdom, but we did have a fantastic EPCOT Center with everything working, including Imagination, Discovery Island, River Country, the Polynesian Luau (without Minnie) and other dinner shows (Broadway at the Top? -- not sure if that was still going), the longer Country Bear Jamboree with the Christmas and Summer overlays -- and the animal heads continuing to talk to you in the Mile Long Bar after you left the show -- a LIVE and energetic Christmas parade that wasn't a plastic infomercial, 20,000 Leagues Under the Sea, the Mike Fink Keelboats and other water options on the Rivers of America, the great water feature at the Polynesian, and more. And, of course, the Disney-MGM Studios park was on the horizon.
No, it wasn't as built out as it is now, but it was truly a resort with detail taken everywhere; and you were treated like a real guest. That I would take again any day,
