I just went to book the CME shared shuttle through their site, and the time slots it gives me available are not very close to my arrival/departure times entered. My flight lands at noon, and the closest shuttle pickup time it gave me was 2 PM. My return flight departs at 3 PM, and the latest pickup time available at Keystone is 10:30 AM. I was wondering if anyone else is having the same issue? I was really hoping to get to the conference by starting time, but with 2 hour wait at the airport and drop off shuttle time scheduled at Keystone at 4:40 PM, I am going to barely make it by the time I check in. Do you happen to know if they might have more time slots available, or is this as good as it gets? Also, if I wait any longer, will I have even fewer choices left with more wait time at the airport? Thank you in advance for any feedback you can provide!
