I also found out the shuttles are considered Mass transit and don't require car seats for infants even. It makes me nervous, but do I really want to carry it with us?
I don't believe that (the info, not you...you're just saying what you found) for even a second.
Car Seats and Pets
While laws vary from state-to-state, we at SuperShuttle support the strongest safety standard by recommending that small children 5 years and under be secured in a child restraint seat for transportation. Additionally, SuperShuttle does not provide child restraint seats. It is the reponsibility of a child's parent or caregiver to provide the Child Restraint System when transporting children in van and/or taxi cabs.
The shuttle vans have seatbelts, therefore you use carseats.
The buses however, are like any coach bus. No seatbelts, just like at WDW I hear. Therefore, no carseats.
The arrival time is tricky when using Grayline, most definitely! We got there just too late...we could have hurt ourselves to get our bags and out, but I'm sure we would'nt have made it. So we took our time, dawdled, etc, for the bus coming next (an hour later). Since I knew that was going to happen it wasn't as big a deal as it could have been if I didn't expect it. We also ended up walking up a few terminals, to stop the boredom and to get on the bus a couple minutes earlier.
It's pretty weird that the PP's bus didn't stop at DLH first, that's what they are supposed to do to work out transfers and such and payment. Strange.
The mousesavers thing mentioned the shuttle van calling themselves DE, oh yes, we saw them, AND we saw a BUS pretending to be DE! I pulled out my printed voucher, though, and they ran away. They're looking for the people who have not paid online, who can't really hear what they are saying in the loud drive area that you wait in...I read that some of them will actually carry a DE brochure (they do it to say they charge the same, but of course it LOOKS like they ARE DE). Our voucher caused them to leave us alone, yay.
I've used SuperShuttle, rental car, and DE for LAX. All have good and bad points. I'd use any of them again!
