John Wayne is closest, theres also LAX, Ontario and Long Beach for price comparisson. But also compare car rental rates between them too.
Knotts Berry Farm is cool and the closest amusement park to Disneyland.
Hotel options, use expedica.
Use google maps, put in disneyland ca
on the map put in search nearby motels, or hotels, and get listings too.
You can easily do both parks in one weekend. Theres also a water park next to Knotts, or a giant giant one called raging waters in the cit of San Dimas, my family loves Raging Waters, its an amusement park, not a golf land with a few slides.
