Theme park companies are taking extra measures to promote social distancing once their parks reopen. Six Flags (NYSE: SIX) announced on Wednesday that all its guests will need to check in through a reservation system that limits park entries by date and time. The move is aimed at minimizing the chance of viral outbreaks in a system built to entertain large numbers of guests. Peers like Cedar Fair (NYSE: FUN) have announced similar adjustments to the ticketing and park experiences. "We are excited about reopening our parks and getting back to the business of fun," CEO Mike Spanos said in a press release. "However," he continued, "we want to do so in the safest possible manner."

Priority will be awarded to members of its various loyalty programs like Diamond and Diamond Elite. The sign-up process will take between 5 and 7 minutes and includes a video that describes new social-distancing and sanitization procedures in the parks. But Six Flags is hoping that the inconvenience will be a small trade-off for operations that meet the latest safety guidelines from the CDC. 10 stocks we like better than Six FlagsWhen investing geniuses David and Tom Gardner have a stock tip, it can pay to listen.
