  • Note: This table reports simulated results for a $5/day fee for residents of Florida, Alabama, and Mississippi, and $10/day fee for others. All estimates except avg. fee per trip are reported in millions. Monetary estimates are in 2012 $s. Price elasticity of demand for trips to Gulf Coast sites is approximated by the percentage change in average price divided by the percentage change in trips to the Gulf Coast.
