Spirit class 4K verses 6A

[canyoncam]

Booked a 4K (4141 with more somewhat of a view) for Hawaii 2024. The savings over a regular ocean view isn’t huge but enough to cover my drinks for at least half the cruise 😉 

Since it’s so far out I could budget the 6A but I won’t be in the room a lot. My concern on the 4K is noise or crew being on the deck as I like to have my drapes open-especially during daylight. Light from outside bothers me at night too so I usually sleep with closed drapes if at a hotel in the city but on a cruise if I have a balcony or window I leave drapes open to let me awake with sunrise so another concern is lights at night. 
Should I upgrade? I feel the answer is yes but I like reinforcement 🙂
