After receiving emails for 2 weeks with an advertised rate of $514.00 I finally called their toll free number to speak with an agent. Maggie fielded the call and had the same result I did, the $514.00 advertised fare was near double ($990.00).
When she told me the fare was no longer available I asked her why I am getting emails for 2 weeks from their partner Cruise Critic. She then told me she has had this happen before but be assured they have a very good record with the Better Business Bureau. AHA.
