If you are looking for a relaxing cruise and a great price and fun port, then I would recommend the Valor. I have over 125 cruise days with Carnival on 14 of their ships. I have never had a problem on any cruise.
This was our first time on the Valor. Since we love visiting New Orleans, it seemed like the perfect time to bring my Mother-In-Law on her first cruise. Getting to the Port took a lot longer because of road construction and the Essence Festival activities. Regardless, we made it during our assigned time and walked onto the ship in about 10 minutes.
While the Valor is older, it does have some of the food venus of the new ships. The big piece missing was water works which would have been nice as it would have given people more places to cool off as this was hot and humid cruise.
Overall, the cabin was great. We had two cabins on this cruise. Ours was 7218 and the kids were in 7214. The rooms were nice and clean with plenty of storage. The tempature was little warm though. While it is nice to have a window, it was not worth the extra money since we spend so little time in the cabin. Plus it is nice and dark for when you want to sleep in.
Great Port city to spend a couple days visiting either before or after the cruise. The Port is easy to get through. I have gone through New Orleans several times and it has never taken more than 30 mins to get on the ship once we arive. The key is to arrive at your assigned time.
