We LOVE Cabo.

I would recommend snorkeling, or at least go out to, Lovers Beach (Playa del Amor). It is a really cool place.

Medano Beach has a lot of fun things to do as well.

Las Guacamayas is a great place to get tacos. So good

We took a cruise around Lands End, it is a pretty cool place, very low key and not sure how much it would entertain kids.

Swim with Dolphins. This one is a bit pricey but is probably the most memorable thing to do with your kids.

My personal favorite: Cabo Wabo Cantina. A restaurant owned by Sammy Hagar. Has some great music memorabilia, and they usually have bands playing in the evenings, plus the food is good as well. Not sure what they are doing with COVID Stuff, but we really enjoyed it. I am a huge Van Halen fan so my bias is coming out on this one.

If you enjoy fishing they have some great options as well.

The food down there is AMAZING, so you can't really go wrong with any joint, but other favorites (outside of the above mentioned are) that are on the cheaper side would be Sanchos Sports Bar and Mariscos La Palmita.

Hopefully, this gets you started with some ideas. Now I want to book a trip down there.
