Did not have an obstructed view cabin on Ventura, but our daughter has had 2 on Oceana. One was between lifeboats and the view was ok. the other the only way to see anything was through the lifeboat windows. But at least you know whether it is day or night. Regarding Ventura! We had a lady come up to our table near the breakers bar absolutely red with embarrassment, she had a cabin obstructed by the lifeboats and had gone to change into her swimsuit! Needless to say when she was starkers someone had decided to clean the windows! Obstructed view! We do not think so! So beware!
I am due to go in a restricted view cabin on Island Star in a few weeks, so can write more after that. However, I do know what I was told, which was if you book your cabin specifically to be IN BETWEEN two lifeboats then the restriction will be minimal. This is what I have done, Island charged £30 to book specific cabin, so I will write a review afterwards, I only hope it is not a complete waste of money!
We always book ''fully obstructed'' cabins on the Artemis as only 1/4 of the picture window is blocked--so a good view and plenty of daylight for a ''good'' price.
We travelled on qm2 with an obstructed view and it was fine. we could only see by standing at the rail but it was nice just to have daylight in the cabin but some are more resticted view than others ,have a look on the ships layout plan re the position of the lieboats.
