We will also be on the Navigator 12/28 and are traveling with our 2 teen daughters, 19 (she'll be 20 in February) and 16 (she'll be 17 in March). We are also traveling with my parents who are celebrating their 50th wedding anniversary. We were originally booked on the Explorer but switched to the Navigator. Be sure to go to
