Hi Katie!
I've taken both my kids at pre-school age (son as early as 18 months) so I completely understand the question.
Here is a snapshot of rides, activities, and events my pre-schoolers thoroughly enjoyed at the 4 parks:
Magic Kingdom
•It's A Small World!
•Buzz Lightyear's Space Ranger Spin
•Dumbo Ride/Mad Tea Party-Fantasyland
•Mickey/Minnie House-Toontown Fair
•Peter Pan's Flight
•Disney Railroad
•Magic Carpets of Aladdin
Epcot
•Imagination Pavilion
•Innoventions
•The Seas with Nemo and Friends
•Kidcot Fun Stops at World Showcase
•Journey Into Imagination With Figment
Animal Kingdom
•Kilimanjaro Safari
•The Boneyard
•TriceraTop Spin
Hollywood Studios
•Playhouse Disney-Live on Stage!
•Honey I Shrunk the Kids Movie Set Adventure
•Toy Story Mania
This is by no means a complete list, but hopefully shows that Disney has a lot to offer to even our youngest.
And you're correct that most thrill rides do come with the Rider Swap option. You can go to the Disney Attractions link by clicking here, then on the left menu under "Features," check the Rider Swap option and attractions will filter by those with Rider Swap.
Have a super magical time on your November trip!
