Well, I emailed them about an itinerary

My flight lands at 11 AM, so it is not too bad a schedule for some of the adults in our party

With rental cars so high I was going to rent a minivan and send the 3 extra people in our party on this route to save $$$. I am still hoping the rental rates will come down, so we can get 2 vehicles

It looks like I will have to email closer to our arrival to get an up to date itinerary. Anyways, here it is:
Thank you for your Lynx travel inquiry. Below, I have
outlined a trip from airport to the Transportation/Ticket Ctr. (TTC) at
Disney. This trip can be made at 30-minute intervals on Monday -
Saturday. If you are arriving after Aug. 12, there will probably be
some schedule changes involved. Once you are at the Disney, TTC, Disney
will get you to your destination on property.
*At the Orlando International Airport, make your way to the Main
Terminal, Side "A", level 1 (the ground transportation level). Lynx
buses leave there from spaces 32-33-34. Board link #51 at 11:33 a.m. .
As you board, deposit $1.10 in exact monies and ask the driver for a
"transfer". You'll arrive at the downtown Orlando Lynx terminal at
12:20 p.m. .
**At the downtown Orlando Lynx terminal, go to lane 1 (the "red" lane),
bay-letter "D". Board link #50 scheduled to depart there at 12:30 p.m.
. As you board, just give the driver your transfer. You'll arrive at
the Disney Ticket & Transportation Center (TTC) at 1:12 p.m. .
***At the Disney TTC, Disney itself has FREE transportation to ALL
Disney destinations at intervals of every twenty minutes or so. When
you arrive at the TTC, just go to the information window and tell them
which Disney destination you wish.
