We used the Mears shuttle last year to go to Universal and for us personally, never again! The pick up times were alright, we were told pick up was 7:30, 8:00, 8:30, 9:00, 9:30 and 10:00. While we were at Universal, we had to call them for a pick up and given them 2 hours notice. They picked up ever hour from 4PM until an hour after the park closed.
Our driver in the morning was SO rude to us! He turned up early (no drama for us) and practically yelled at us to hurry up and get in. We were absolutely packed in like sardines. Upon arrival at US, we paid the driver and gave a $10 tip (it was only 2 of us) to which he replied "Gee thanks SO much for the HUGE tip!" We were stunned!
In the afternoon, we called for a pick up like we were told. The operator offered us an earlier pick up time, since there was already a shuttle coming to pick up other people. We took that one (we were ready to leave earlier) So we headed out and waited for the bus. It arrived, we gave the driver our confirmation number and again, he was so rude to us, saying that we couldn't be booked on HIS bus since we had only called an hour earlier. We insisted that we were, he checked and indeed we were. We got on the huge coach and waited 45 minutes to go anywhere! There were alot of other people on the bus as well, it wasn't half full. After this, we stopped at Sea World as well so it took us almost two hours to get back to WDW!
We wouldn't ever use the Mears shuttle again. It cost is about $25 each for a return to Universal but it took us at last two and half hours round trip. An estimated taxi fare is $36 each way and we would absolutely take a taxi next time!
