Since you can hold the reservation for now without penalty, JW is supposed to have just finished their renovations and someone who post here regularly is going to the hotel soon, you may want to wait until we hear a trip report before making a final decision. In the meantime it would not hurt to hold other reservations as backups. A few questions. Is this your first trip? Are you someone who cares more about upgrades, the concierge lounge, or being able to easily return to your room throughout the day?
