We love the Edge class ships, especially Apex and Beyond. We have been in sky suites, Aqua and Concierge class and love them all. As far as the IV balcony, we like them. We have more cruises booked on Ascent, Beyond and Xcel with the IV balcony and look forward to them all. The only way you will know is if you try it. Our last cruise on Beyond was great. No issues and enjoyed it all!
