Here's what I found:
The Magic Kingdom opened with 26 attractions: Jungle Cruise; Swiss Family Tree House; Sunshine Pavilion (Tropical Serenade); Cinderella's Golden Carrousel; Dumbo Flying Elephants; Mad Tea Party; Mickey Mouse Revue; Mr. Toad's Wild Ride; it's a small world; Snow White's Adventures; Diamond Horseshoe Revue; Frontier Shooting Gallery; Country Bear Jamboree; Mike Fink Keel Boats; Davy Crockett's Explorer Canoes; Hall of Presidents; Haunted Mansion; Main Street horseless carriage, Jitney, fire truck, horse-drawn streetcar and omnibus; Main Street Cinema; Walt Disney World Railroad; Skyway to Tomorrowland/Skyway to Fantasyland and Grand Prix Raceway.
The Admiral Joe Fowler Riverboat opened the next day, Peter Pan's Flight the next, and 20,000 Leagues Under the Sea two weeks later. That made for a grand total of 29 attractions open before Dedication Day, 30 if you count both directions of the Skyway. By the end of the year, Tomorrowland was a bit more populated, with “America the Beautiful” opening in the CircleVision Theater in November and Flight to the Moon opening in December.

Cool pics! Love went when he was 2 1/2 in 1972 (I've got some pics
here) but I wasn't even born yet. It's always neat to see old pics like this.
