Hi Luci, I've heard the doors do open but you can't step outside, you do get a large window but it's obstructed by a lifeboat. I've never done a french door just considered it, I would love to see on in person, so if you ever get the chance check one out. Maybe a room steward could show you an empty one on the Splendor?
I have considered upgrading my 1A to a window cabin but my roomate figures we save $100 on this cabin which we can use towards a hotel in port or shore excursion. If I decide to upgrade on the ship do you know if it costs a lot more? Also we are cruising in September so that should mean way less kids on board, since they are back in school correct?
