This was an interesting read on this topic. We started out doing balconies or Jr. Suites on our first few cruises. A lot depended on itinerary as to whether a balcony was needed. As we cruised more, we started doing interior cabins for Caribbean itineraries we'd done so many times. . Being that we both worked too many hours, the dark cabin where we could sleep late was a real luxury!!!
In recent years, circumstances have required that we take separate vacations (elder care issues). I really didn't mind interior or promenade cabins when sailing solo. Promenade cabins seemed great for the extra light and space.
As we've gotten older, we appreciate balconies more. We are now getting ready to sail together for the first time in several years (post elder care/post covid (hopefully)). We were fortunate enough to win a RoyalUp bid (first one we ever bid on) to go from a Jr. Suite to an Owners Suite. We will probably never be lucky enough to get such a great price on an OS. I hope it doesn't spoil us.
Lately, Covid has us thinking our own balcony is a really good idea for a safer place to hang out.
