There are some nice views of San Marcos from Staples Road. I'd bring a telephoto/zoom, to pull the city in and position the people as far back as necessary, to fit in the frame. People often make the mistake of zooming in/out to fit the people in the frame, leaving the background less than optimal.
The people can move. The city can't. Find a nice spot, compose a shot of the city and then put the people in.
