Natatorium in San Juan, Puerto Rico?

Hi all- This is my first-ever post here... I will be traveling for a work meeting in San Juan, PR in a couple weeks. While I am there, I would love to be able to swim at the San Juan Natatorium, and even better if there's a masters team to drop in for a workout with. I am having trouble figuring out public swim hours from the pool's webpage. I recall that LCM nationals was there a couple summers ago, so I am hoping someone is familiar with the pool and can give me some basic info. I am trying to "collect" visits to new pools & swim workouts in as many states and countries as I can! Thanks for your help with this! --Margaret
