First off, allow me to apologize for the inconvenience you experienced. The only rooms that may be off-limits depending on the proximity of the sail date, are modified stateroom which are held specifically for our guests that need wheelchair accessible staterooms. However, in order to correctly respond to this I would need to have explicit details such as the promo you were trying to book and which category or stateroom you are referring to. Please reach out to me personally at nhernandez2@carnival.com.
