Having fun with toddler means also having some rest for parent while you are enjoying seeing your beloved toddler having fun in safe environment.
As such I strongly recommend a few places in different sides of the world:
Warsaw ( Poland) : Copernicus Center.
Los Angeles ( USA) : Zimmer Children’s Museum
Cascais (Portugal) : Parque Marechal Carmona
In every listed place you can have some rest as parent while watching your child having fun and play as well
educating while playing.
