Last December 2, we departed Barcelona on the Brilliance of the Seas for a 15 day to Ft Lauderdale. We normally do 2 transatlantics per year (spring and fall) but this was the latest we have ever returned from Europe. It also turned out to be some of the best weather we have ever experienced. The seas were relatively calm the entire way across (never more than 6 feet) and nearly every day was warm (70s) and sunny. In April of 07 we did the Jewel of the Seas from Miami to Rome, and this cruise had the most dreadful weather we have ever experienced in more than 50 cruises. For 3 straight days, the seas never dropped below 30 feet (often quite higher) and it rained nearly every day. The bottom line is that when you cross the Atlantic its like rolling the dice, and there is no way to predict.
