There are some things I love about the Carnival Magic, but some of the overall changes by Carnival (shorter port times, fewer dining staff, no adult pools, etc.) will certainly make me consider other cruise lines.
I've already booked all the new ships scheduled for Galveston so there will be fewer on CCL for sure. That's just a personal choice by me. People will have a wonderful cruise at a pretty fair value on the Carnival Magic, but unless friends are sailing I'm probably 'done' with her. Too many other good choices.
