Reserve at the HI Express but keep checking the Westin for cancellations. I cancelled my room there last year when business took me to Orlando. This year, while I plan to go and have paid for my Expo registration, I still might have to cancel if an emergency occurs. This could happen to others and a room at the Westin could become available. It is a nice, full-service Hotel that is just under 10 years old and has had one refurbishment already.
