My wife and I did 3 7 night Fantasy cruises last year. All were supposed to be Eastern with same ports. The first was in Feb with just the two of us for our 40th anniversary. The second was in July, again to celebrate our 40th, but this time with our 4 adult children and their families. The 3rd was just the two of us again, on a Merrytime cruise the week before Christmas. That one ended up being a Western due to hurricane damage to the Eastern islands. The cruises were mostly picked based on when they were, rather than where they were going. The summer cruise was scheduled based on school schedules from three different states. My wife's work schedule it tied to our local school calendar, so we choose the week before Christmas when they started their 2 week winter break.
