Give me a suggestion where I should go for spring break if I live in the United States.

Florida is a very popular location for families to visit for spring break, because the weather is generally very warm and sunny which makes it easy to do outdoor activities. Popular destinations in Florida include theme parks like Disneyworld, Universal Studios, SeaWorld, Legoland, and Busch Gardens. Florida is also known for its many beaches where you can go surfing, boating, and sunbathing. 

Another fun location for spring break is Cancun, Mexico. Many college-aged adults will go to Mexico and stay at a resort. Popular activities include drinking, partying, and going to the beach. This option is probably better for families without young children.

A third option is visiting Southern California. Like Florida, the temperatures will be warm and sunny. San Diego is a good place to visit, as it offers many beach activities, but if you don't want to go outside, there are many museums and parks to visit, such as the San Diego Air and Space Museum or Balboa Park.
