Thinking about renting a car in PR🇵🇷

So I’m going to PR to see Benito in Aug. first of all how is the parking situation en el Choli during a concert? My hotel is abt 11 mins away. Should I uber? I’m also thinking about staying an extra 2 days after the hotel experience is over. And second what’s a best car rental company to choose in PR? I keep seeing that Alamo and Enterprise are great, but which one do y’all recommend?
