I sincerely thank all of you for your input. Since I am on my way to SIN I only have summer stuff to wear, so as this point I am planning on toughing it out in the terminal landside. It's only a little more than six hours, I think it's doable. The Fairmont showed as unavailable and if I read it correctly, it's past security, so not reachable for me. Thank you again, it is really helpful.
