An economic downturn in Mexico caused tourists to flock to Puerto Vallarta. In 1982, the peso was devalued and Puerto Vallarta became a bargain destination for US tourists. Consequently, the mid-1980s saw a marked and rapid rise in the tourist volume. This uptick fueled additional development, for example the Marina which was started in 1986. But Puerto Vallarta's success caused other Mexican cities to take note. The early 1990s saw Mexico's government and private business develop other resort destinations, such as Ixtapa and Cancún. This took away Puerto Vallarta's exclusivity of sorts on the foreign tourist trade, and caused a slump in travel to Puerto Vallarta.
