Okay, so many, but pertinent, questions.
All pools can be seen from the public areas, including the front row tables in the restaurant. There are no 100% totally private pools.
The pool beds are mostly in the sun. All views from beds/pools are fabulous.
As one’s requirements are quite personal and specific, as to what one would consider “the best”. Therefore, suggest a scroll through all photographs, take a screenshot of the pool desired, then phone and discuss one’s selection, in detail, directly with SR to book one’s desired position. SR are nice people and will be happy to help.
