I'm pretty sure that I know the answer, but with the new addition of business class I'm finding conflicting information and just wanted to clarify.
To stay business class, you do NOT need to be a convention guest. Anyone can now stay business class, whether you are a vacationer with your kids or convention guest, correct?
9B is now totally business class. If you want to stay 9B you need to book business class. Or are there rooms still in 9B that aren't business class rooms?
Thanks!
