It seems hotels are always extra cautious about the time it takes to get to and through airports. At least, that's my experience.
Thanks to you (and others) for all the help in this thread.
Off to Terminal 2E in a few hours. We may take Uber, just out of familiarity, unless it has excessive wait times or charges.
