We cruised on LOS on the last cruise of the 2011 season from Barcelona the week of October 22 to 29. We were in a balcony cabin midship on the 7th deck.
After spending two days in Barcelona prior to the cruise we proceeded to the dock around noon on the 29th. After dropping the bags with the porters we were checked in a very short time and ready to board. Interestingly, the security screening was performed by Barcelona port personnel and not those of LOS. Just after the bag screening and body scan there were several shops including some that sold wine, beer and hard liquor. We purchased a couple of bottles of wine for in cabin use, placed them in our backpack and proceeded to the ship. There were no more security checks and no one asked to see in our backpacks.
We were not able to go to our cabin until 1pm so we went off to Windjammer for a light snack and then explored the ship. The ship was in excellent shape, clean and neat and showing no signs of wear and tear that we could see. The food we had in Windjammer was good and this was one of the two times we ate there (the other being on the day we left the ship for breakfast). This has nothing to do with the food quality but the fact that we dislike buffets and the inherent risk of disease being spread by too many dirty hands touching all the food.
