It’s renewal time for Heat and Panthers season ticket holders and both teams are offering incentives to entice fans back.

The Heat is lowering or freezing some prices in the upper levels at AmericanAirlines Arena and charging 100 level ticket holders $1 to $5 more per game, although prices could be quite a bit steeper if you had a three-year contract that just expired. The team is still offering one-year and three-year renewal options, with the longer contract including larger savings.

Current season ticket holders must renew by March 21, but if they do so by March 7, they’ll get a limited edition 20th anniversary Heat wristwatch. In addition, the team is scheduling a number of activities for fans who renew, including a “Speak to the Heat: Season Ticket Holder Town Hall Meeting,” during which season ticket holders will get to ask questions of Heat owner Micky Arison, head coach Pat Riley and President of Business Operations Eric Woolworth; a chance to stand with the players on court during the National Anthem; and a series of parties with Arison and Alonzo Mourning in an arena suite.

Those who renew by March 21 will also be entered into a sweepstakes that includes prizes such as two free lifetime Heat season tickets; a 42-inch plasma TV; gift cards for gas, groceries, and Dunkin’ Donuts; a chance to be “broadcaster for a game”; your property tax or FPL bills paid; or a one-year membership to 24 Hour Fitness.

Meanwhile, the Panthers are freezing prices for season ticket holders who renew by March 14. Those fans will also get 5 percent of their investment in “Panthers bucks,” which can be used to pay for concessions at BankAtlantic Center. In addition, the Panthers want season ticket holders to be actual “seat owners” with even more of a say in the franchise.

Panthers privileges include personal nameplates on your seats; a team windbreaker; access to an exclusive “season seat owner” section on the team’s Web site; special team road trip travel packages; quarterly shareholder meetings; and priority playoff benefits.

Are you renewing for either team? Do these incentives make a difference? Are you giving up your tickets? If so, why?
