Is there a sensor check in Disneyland? (Disneyland & California Adventure)?

When you walk through security they use a metal detector wand that they pass up and down your body front and back. If it beeps because of a belt buckle all you will need to do is show them that it is a belt buckle and they should pass you through. If it beeps a lot then they might have you remove the belt and scan you again to be sure you are not hiding anything and masking the beeps with the buckle but that would be about it.

There is one screening tent from Downtown Disney into the "Entrance Plaza" (area between the two parks) and one coming from the tram/bus loading and unloading area. You don't have to go through them again when you change parks.

No, Disneyland does not have Metal Detectors. They only have a bag check where they will need to see any bag you are bringing in.

Also, if you have a bulky winter coat they will ask you to open it as well.

No idea.

Solution: Wear a belt without metal.

:O

There's no metal detector. Don't worry about it.
