We have just returned from a 10 night cruise on Queen Elizabeth. We sailed in a P2 suite (4096). Great position on the ship with larger balcony so would recommend the cabin and that next to it (4094). There is a crew access point to deck 4 opposite 4098 so would avoid that one. Link below shows a video of 4096 and then also the Grills Terrace.

There has been recent comment re the new PG menus that were recently launched on QE. These are not yet on QM2 or QV. Firstly can I say that we had a fantastic PG experience the service and food hit the mark for us - we travelled as a party of 6 with a fantastic window table. It reminded us of the things that we came to expect on our first few cruises some 16 yrs ago on the small P&O ships Oriana / Aurora. Naturally all that time ago we were paying some £2,000+ per person for a balcony prior to the industry wide discounting and service / quality cuts that are a natural consequence.
Great cabin
No need for excursion - use taxi and trams. Worth a visit tio the castle.
Not a great place but friends did Fire Mountain and loved it
Great if you go to Santiago de Compostela
