I felt safer in Cabo than Austin. Restuarants are very spaced....and EVERYONE is masked up inside and outside. Temp check at restaurants and everythign is being cleaned constantly. They are doing a good job.
I did see a nice course when we were coming in. If you are going for a few days...the resort thing is a good option as it does seem nice...but town is super close and there are a couple nice restaurants and that taco dive you might want to hit.
If you are there for a week...I would try and golf if you can...I would personally be fishing...some of the best marlin fishing around...I also did a two-tank dive because I have to get underwater to decompress from life outside of it.
If you get a serious bug...your wife might like this place: https://www.flora-farms.com We took a salsa making class using a molcajete and taught by their head chef....a lot of fun and damn good recipes. And again, not only all masked up...but some of the most advanced masks I have seen are at this place...these clear plastic small shields that are supported at the chin and just cover the mouth and nose from @ 1" away so you can see the person as they talk. They also have a signature carrot margarita that is 'lit' as my kids would say.
Enjoy!
