Visiting Pompano Beach!

Hi folks. My mom and stepdad are visiting your fine city for two nights. They're landing in Ft Lauderdale, and she plans to rent a car for the two nights.

The activities are a wedding reception and a brunch. I'm wondering, would it be more cost effective to just take Ubers or the equivalent? She's going to try and find the locations specifically of the hotel and restaurant she'll be going to. It's really an Uber in, an Uber out and maybe one or two trips in between. We're Canadian so the conversion sucks but I figured I'd ask anyway.
