Wow. Am I glad to get this news before leaving!! I will make that happen for sure. Thank you so very much!!

overplanner - Let me add this. With the three possible ways of getting from 2A to 2F, I usually suggest walking. I've never heard to excessively long lines through entry immigration at 2A, and you don't need to worry about the bus. It may not be the fastest, and you have to walk (~15 minutes), but it's the most reliable way.

If you are capable and don't have excessive carry-ons, that may be the best method.
