The weather should be nice and warm with plenty of sun, great time to go before it gets really hot. Also, try posting on the "Meet on board" here at Cruisemates for finding other families on Victory the same time, good luck and happy cruising:
My husband and I are sailing on the Victory 4/29 to the Western Carribean. First time cruisers so we are very excited. We are bringing my son, who is nine. He has no idea we are going. Keeping it a secret. He still won't know after we get on the plane, as we are planning to spend the weekend with my sister-in-law in Florida.
Let me know how old your children are. Maybe they can buddy up.
Looking forward to hearing from you. I was starting to think we were the only ones traveling with a child.
