19.Can I request a Suite Night Award upgrade for more than one room at a time?
Yes, if the additional rooms are part of your reservation, you can request an upgrade as long as you have enough Suite Night Awards to cover the entire length of your stay for each room. One Suite Night Award is required per room, per night.
