Three additional ways to save depending on how generous Princess is feeling at the time. Your mileage may greatly vary!
1. Gambler fares: You may only pay port fees, get a white lanyard for free drinks in the casino, captain’s private party at times and a black card. You may also get free air.
2. Move over fares: When the ship or cabin class is oversold your original fare may be refunded and a free future cruise or at least a free different level cabin may be offered. Sometimes future on board credits may also be offered. These move over deals are typically offered to those living near the embarkation port.
3.. Suite upgrade offers: If you receive this offer you have to move very fast but beware - Princess has lately been making this offer pretty pricy.
