Just wanted to post a short review as we just got off of the Miracle to the Mexican Riviera. We've sailed on Carnival before (as well as Holland America, Princess, Norwegian, etc). Also, we've sailed this route before and didn't have any plans to even get off the ship.
I was sailing with DH, my DS (13) and DD (10). We were in Ocean Suite 6158 on the port side.
We had driven to the port the day before and Saturday was beautiful so we walked around Long Beach and rented a little boat for an hour and drove it around the harbor and around the Miracle which the kids thought was really fun! It was HOT day!! We could see that people were still disembarking around 11:30 and around 12:30 just starting to cross the bridge onto the ship.
6158 on the Port side of the Miracle was a great room. No interior room across the hall, midship. 2 electric outlets. One in bathroom, one behind TV. Large balcony with 2 chairs, table and a lounger (one of the chairs also reclined). This is a quad OS with a couch/bed and a pull down bunk.
