We used the Car Care Center on our last trip.
Had major issues with the shuttle..we had called to book it & could not get thru..not at all..it just rang.
We went down to the desk at POFQ to see if maybe they had a different number we could try..they didn't..but tried calling for us..same issue..they then started to contact them thru other Almao numbers to no avail..this was taking forever and we needed our car to get us where we were going on time.
The CM at POFQ felt terrible that we could not get the shuttle..she called someone and along came a lady & a van and she personally drove us over to the Car Care Center! (Turns out her brother was living in wpg..small world!)
So..my advice is to try calling far in advance for that shuttle!!!
