How much would it cost to get from New Orleans to California?

My fiancé and I want to road trip from New Orleans to Los Angeles and back. He said he'd like to stop in the Grand Canyon and we have family in Los Angeles to stay with so we'd need to stay in a hotel maybe 2 nights total? For food, gas, hotel, etc what would be a good price? I drive a Honda Accord so it's great on gas. Just a rough estimate would be nice

Remember that worthless algebra class you took in high school? Well, dust off your notes, and make a realistic plan and budget, because we do not know enough about your plans to do it. "Road trip" means you will be seeing things along the way. Goofle, tour books, and state tourism offices can give you many options to pick from.
