For another perspective: We are paying $163 pp/pn for our upcoming Equinox 9 nighter in a balcony on 9. Our upper limit probably would be @ $225 for a balcony on X. (Our first cruise was 10 nights in Aqua in April 2019 for $220 pp/pn.)
Had a balcony on Allure in October 2019 for a 14 night b2b that cost us @ $128. Too much for the Central Park balcony we had, but I was not willing to go up to $150 for an Oceanview cabin.
We don't have the resources to spend more, but I retired at 50 and the tradeoff is well worth it. I admire those who worked harder and longer and earned their suites, but I am not envious because the Retreat deck, the drink setups, the butler, and Luminae would be lost on me.
Now, the extra space...oh, well, leg bruises go away in a week or two!
