We were on the 5/3 sailing and the seas were rough on Monday, the 1st sea day. We were in the spa section on deck 10 in a balcony room. I took meds and still vomited 3 times on that day. We ran into a lot of crew and passengers who were very sick as well.
Barff bags were no where to be found, I thought that was strange. On a previous cruise we encoutered rough seas as well and Princess had bags very visible in public areas. Needless to say twice I didn't make it to the bathroom and made a mess but with no bag what can you do? After that I asked for a bag while in the spa section, and they gave me a spa gift shop empty bag and on most sea days when I was feeling queasy I walked around the ship with my little spa bag, just in case I need to use it.
The buffet food was good, no complaints - as many have said here, you will not go hungry in fact you might pick up weight on the Splendor easily.
