Cabo San Lucas is known by some as a party destination for American and Canadian tourists seeking to get out, get drunk, and get dirty.  However, Cabo San Lucas and San José del Cabo (which together form Los Cabos) tend to be far more classier than their Mexican counterparts such as Tijuana, Puerta Vallarta or Cancun.
