Quick Question! (Umbrella rental!)

Hey ya'll heading to Fort Lauderdale for a 10 hour ish day trip with some friends. Flight gets in at 9:30am and leaves for home at 8:15pm.

Any suggestions for a beach close by to the airport for 3 20 year olds?? We really just want to hang out, swim, drink, and grab some good food. I was thinking Las Olas for the day? Thoughts?

Also! More importantly, where should we go to rent an umbrella for the day? I burn so easily so I'm willing to pivot plans to guarantee an umbrella rental lol.

Thanks!
