Laine,
As of this point I have not yet been on the Grand or ever stayed in a mini-suite.
But, will be on the Grand in July & have been on sister ships.
Cabin selection is always up for debate. Some say do not spend the money for balcony/suites, while others go for it.
Most do not spend a lot of time in the cabin to require living space per say. But, always nice to have the room.
Aft cabins are usually sought after by most. However, I would think you may hear some right above the stage. Most suites are aft with the wrap around balcony.Offering great views of course.
I stayed in an aft cabin, but, higher up on Aloha. Did hear an occassional deck chair early mornings being dragged & set up.
Most balcony cabins I have had have been on Deck 12 - Aloha. While Carib balconies can offer a larger sized balcony.
Hope this helps. Good Luck with your decision.
I am sure you will get more opinions.
Happy Holidays!
Cathy
