My two girlfriends and I did a girls trip out of Galveston in July on the Breeze. And in Oct 2017 I did a girls trip on the Vista out of Miami. Both were amazing. Me personally, I look at a ship that has more to entertain us and would pick the Vista. We had no trouble with the lounges and enjoyed every show there was. Granted we make sure we aren't strolling in at the last minute and get seats we favor.
Galveston was so much fun and there is so much to do. We ate at the Saltgrass Steakhouse one night (I think thats the name) and they had the absolute best Salmon I have ever had.
