Just got off the Pride on Saturday as a party of three adults. We started in an inside room, and day #2 we were moved to a balcony room. So last week I had three people and tried out two stateroom categories! Both rooms have the exact same square footage, except the balcony adds extra space outside I guess. Storage space is the exact same. Your cost will be $1,000 extra to get the balcony, so only you know your budget for the trip.
Excursions in Hawaii are EXPENSIVE! I would put the money towards that instead. When you come home, which makes me more excited….the once in a lifetime excursion….or the balcony room? The ports in Hawaii are not pretty, they are industrial, so think of trucks and storage containers. You will be spending all day in ports, not hanging out in your room. There are NO a sea days! Even with a balcony, we viewed the Nepali coast from the outside deck, not our own balcony. Hope I helped. If you need more advice, PM me.
