If you call Mears up to 24 hours before you want to leave, they will arrange a pickup time at your resort. I took a van from CS that stopped at the Swolphin to pick up more passengers, then drove us to Sea World, then Universal. They drop you off right by the entrance to Universal where the building with the moving walkways is. The ride cost $12 roundtrip, I don't know what the fare is for children. They give you a ticket with the phone number on it; you call the number 2 hours before you want to leave and arrange for a pickup. I rode back to CSR on a big Mears bus that stopped at the Dolphin and CBR before CS and was still scheduled to drop by the All-Stars. I didn't consider it a bad way to travel, and much cheaper than car rental for one person. If you've got a big family, the car might be worth it, or going to a towncar service to get transportation for just your party.
