Depends on whether you want quiet or rowdy. Cabo is the rowdy end, with Cabo Wabo and other party bars. There is also a mall with movie theatre, and a Costco, in Cabo.
We did a dinner cruise out of Cabo that was nice. I liked the sightseeing part of it, the food was ok, I wasunderwhelmed by the entertainment.
We prefer San Jose del Cabo. We like to sit outside at The Tropicana Restaurant and people watch.
If you hang out on the beach the market will come to you. Horseback rides, wave runners, jewelry, blankets, hats, ultralight rides, jeep tours, will all be offered by vendors strolling along the beach.
Taxi rides from the airport are expensive. We usually rent a car, which is also expensive because we get the insurance since our US insurance doesn't cover Mexican rentals. We like dealing with Hector at Thrifty. If you are interested, he can fix you up with a big discount off your care rental in exchange for sitting through a time share presentation.
We enjoy driving along the coast to Todos Santos and hanging out in the cafes there. You can also easily drive to La Paz and back in the same day.
