We have sailed Solstice class before on both the Solstice and the Equinox.
The itinerary was the usual Western Med' but despite our numerous visits we had never been to Gibraltar or Cadiz. I am sure some people will tell me that they love Gibraltar and so I apologise to those but frankly I won't be in a rush to go back. Cadiz I researched on the internet before the cruise and discovered that there was nothing there. That is not true. We enjoyed a lovely walk around the town, through a beautiful park and explored the cathedral and a large market complex. It reminded us very much of Cartagena in Columbia.
Back to the ship....
7153 and 7155 Close to the elevators so not too far to walk! Very well laid out. Wardrobe space and cupboards are bit limited but we managed and we had clothes for eight weeks! The bathrooms on the Solitice Class are very good, probably the best we've experienced. Beds are comfortable. Balcony is exactly as you would expect with good quality furniture. TV flat screen good selection of movies and interactive to view your account.
