I know the last time we cruised, a couple wanted to go with all of us and waited until the last minute - thinking they would get a great deal. The ship sold out...they did not get to go. Sometimes listening to those stories (as they did) can be very misleading. I hated that they missed out on a great cruise.
When they found out the rates of the next cruise we are going on in Sept. dropped to $279.00 per person for an inside cabin...THEY BOOKED.
PS - The rates have almost doubled since then.
JMHO - Hope this helps
