We just used the Super Star shuttle to get to Sea World. The shuttle sucks.
First, we choose to take the 940AM shuttle from the hub instead of the one that left after 10 from the HRH. When we got there, the driver said that they cancelled the 940 because not enough people signed up for the 10am shuttle so they combined them and we woudn't leave until 10. And it still didn't pull out until 10:15am. So much for getting to Sea World when it opened. :-( Then coming home, we planned to take the 545PM shuttle back to the hub. We got to the pick up point at 540pm. At 610, no shuttle had arrived. No 5:45PM shuttle, no 5:55PM shuttle. Eventually we said screw it and got a cab back to the HRH. And I was shocked that when I mentioned my disappointment at the attraction counter at the HRH (had a credit that I used to buy mini golf tickets) after he asked me how my trip was going, he said, "well, it is free, you should be happy that Universal has a free shuttle to take you to someone else's park".
So, the lesson learned here is that nothing in life is free as this free service cost me about 40 minutes of time at Sea World, about a half hour waiting for a shuttle to take us back, the cost of a cab ride, and having to deal with a snarky Universal employee. And to take Uber next time.
