sweetsleep: I live in the UK but am American. I know about hot and humid! My hotel is situated about a half-mile from Centennial Park. I'll be in town early enough to scope out the park the day before. I take your point about trees; I was planning on a hat rather than a parasol and a frozen bottle of water rather than a fan. I am absolutely determined not to drive anywhere!
Sorry you've been turned away from Vanderbilt. I used to know someone who taught there, I think, but they've long since moved away.
