I am currently on board Brillance of the Seas. The current booking offer is second guest 50% off (just like the website), the difference is that where the website says ‘up to $100 to spend at sea’ the flyer in the stateroom says ‘Reduced Deposits are back!...Book your next cruise with us and secure your next vacation with only $100 per person on select fares! Plus receive up to $600 Dollars Off or Onboard Credit, your choice!”
The benefit to waiting: the small deposit and the potential for a lot of on board credit.
The benefit to doing it before you leave home: peace of mind.
