thanks to Kyle I'm able to attend this year's SDCC. There was a plan that before the convention my whole family take a big roadtrip, but it seems that I'm going alone, because other things came up.
So I need some advice. This is my first visit in California (and the second in the States), I'll arrive to Los Angeles. I planned a two week long roadtrip before the con, but alone it would be so exhausting, that I couldn't do it (LA-Vegas-Salt Lake City-Yellowstone-Mt. Rushmore-Grand Canyon and than back to LA, but that is too long, and too much driving).
So I think I'll arrive 5-7 days before the con, so I'll have 4-6 free days. I definitely want to see the Universal Studios, I think that is a whole day program. An other day is a trip to the Grand Canyon. So, for the other days, do you have any sightseeing/program ideas?
Any good places to stay in LA (not too expensive ones

Do you think it's worth to rent a car? Or the public transport is good in the city?
I would like to buy my flight tickets at the end of this week
