What is the “PGC Bonus”

[AllisonJames]

Couldn’t find this info anywhere on the website…prices are quoted with a “20% PGC Bonus”…can anyone tell me what that means? Thanks!

Past cruisers get an automatic 5% off whatever published fare there is, possibly more with more cruises, someone else may be able to answer that. However, the 20%, 25% and 30% PGC bonus is something fairly new to me. I know PGC started using Ponant's pricing strategy which starts at a 30% discount when booking very far in advance and the discount decreases pretty quickly after. They also run the occasional sale for undercooked cruises, although sales are almost always limited to 7 day Society cruises.
