THIS. I've done two inside rooms out of seven Cruises. The first was a GTY with my daughter to save money and I actually liked the layout of the room better with the bed in the back rather than skirting around it to get to the couch/verandah.
The second time was also for cost but I became very sick around the third night with what turned out to be a double ear infection – lots of pain in my face and ears w fever and as a result I was in the room A LOT.

I really needed and wanted some fresh air and light but didn't feel well enough to keep going up on deck, and I swore I would not get an inside room again for this very reason.
One plus I would add tho is that I found the inside room to have a lot less movement than the verandah rooms that I've been in. Perhaps that's just because they were both midship.
