Not anytime soon. Europe maintains high popularity and next year RCI will put 8 ships in Europe. This year the Voyager left Galveston in April to be one of the ships used in Europe.
Here's a little bit of trivia. (For those who haven't already seen the Voyager in Galveston). Did you know when the Voyager is docked in Galveston it flies the Texas flag and has a pair of inflatible Longhorns above the bridge?
