We took the Mears shuttle. Worked great for us. Registered and paid for it at the airport, spouse went to the Magic Express counter to check us in while I went to the Mears counter (next to one another) to sign us up for a roundtrip from AKL to Harry Potter Land (so my daughter calls it). We both finished our transactions at the same time. We called Mears the night before we wanted to go to Universal and they picked us up at the arranged time. We were to call them two hours before we wanted to leave Universal and once again, they picked us up right on time.
