I booked Sovereign in '99 mainly because she was noted as the first of the "super ships." As one who earned a degree in history, I'm already disposed to seek ships with a touch of history built into them. I was already following the development of Voyager as I got ready for the cruise, and I booked Explorer mainly to see what the class was like.
I'm a true fan of the Voyager family, as I expect to be of the Genesis class when they enter service. But there will always be that quality to Sovereign that I can't shake, as my favorite.
I'll just have to keep cruising until I manage to shake that feeling!
