We got stung on the Princess Referral Program!! Don't let it happen to you. This is what I found out:
You MUST refer your friends PRIOR to even HOLDING a cabin. Princess considers a "hold" to be a "booking"....because it is taken out of inventory. This applies to guarantee cabins and specific cabins.
John Q. Public considers a booking to be made once a DEPOSIT is given.
Could it be a flaw in the way they explain this Princess product to the public? I think they need to rewrite this policy.
Just thought I could help someone.
