We had a inside guarantee on our 10/21 cruise on the Zaandam. The price went down $100 per person about 2 weeks before we left and it didn't say only for new bookings. We received the $200 credit and ended up in an "L" cabin on main deck in the rear of the boat. Other times we've booked inside guarantees and ended up outside and one time we got exactly what we booked - the lowest inside cabin. It all depends on how busy the ship is, I think. Check on HAL's board to see if the new price says for new bookings only. If not, ask for a refund.
