Early voting began Monday in Miami-Dade County regarding the modernization of Sun Life Stadium.

The Dolphins say Sun Life Stadium needs at least $350 million in improvements to remain competitive with newer stadiums around the NFL for Super Bowls and high-profile events. Dolphins CEO Mike Dee gave a tour of the facility Saturday.

The Dolphins want $289 million from a 1 percent increase in the hotel bed tax in mainland Miami-Dade County and $90 million from a sales tax rebate.

"It will improve the neighborhood and create jobs," said Joel Scott, who voted for the plan.

"I love the Dolphins. I support my Dolphins. I love football -- [but] we got burned with the Marlins, so no," said Nydia Orta.

The 30-year economic development grant includes a non-relocation agreement. The Dolphins have offered to pay the county and the state back the money it receives from a sales tax rebate of $3 million a year for 30 years.

The state legislature is considering a bill that would authorize the rebate and also raise the hotel bed tax. Under the Senate version of the bill, the Dolphins would have to compete for that money with other professional sports franchises in the state.

The Dolphins and San Francisco 49ers, who will move into a new stadium next year, are vying for Super Bowl L in 2016. The loser will compete against the Houston Texans to host Super Bowl LI in 2017.

NFL team owners will announce the locations of Super Bowls L and LI on May 22 in Boston.
