Thank you for the comparison, I enjoyed your review.
I sailed on the Liberty of the Seas and then 3 months later the Breeze both out of Galveston. The Liberty was my first Royal cruise and I went with a group of women who picked the ship. I was worried about traveling to Galveston, since the port is not close. It was really pretty easy. The worst part was getting off the ship and waiting for the shuttle we had prebooked. When I traveled on the Breeze we booked a private shuttle to the airport, much better. We also booked private from the airport to the port both times. I love the Breeze and liked it better than the Liberty probably because I am more familiar with the Carnival product, but I will say the pool area on the Liberty was much bigger and we really enjoyed it.
I am sailing the Oasis in November with my daughter and family. We did look at Carnival but Royal's sale where kids sail free and the $175 OBC beat out any Carnival ship sailing on the East Coast. Granted, we are in a boardwalk balcony but add the soda packages for the kids, Johnny Rockets and the price can't be beat.
