We booked one of our dummy deposits on the Western Fantasy, March 30 2013 and my DW had an idea to see what the March 24 2013 4 day would cost so we could do a modified B2B. We looked at the cost and decided not to, but last night I looked at our upcoming cruises and I'd actually moved an old MR cruise to the 4 day. Now we can do the modified version of a B2B. DW is very happy, to cruise the Dream and Fantasy. Although, it's pretty bad that I forgot the dates we had book.
