@CypressCajun We have not stayed in an Iconic Suite but hope to LOL. My responses are based on our experience in Penthouse Suites.
We have stayed in the PH on Edge with 2 bedrooms. The 2nd bedroom is on the opposite side of the living area from the main bedroom. The bathroom opens either from the 2nd bedroom or the main living area, Jack & Jill style. While maybe a different layout in the IS no room divider will be needed.
Unlimited specialty dining includes everything but Dinner on the Edge, Chef's Table and tasting menus in restaurants like Eden. Everything at Raw on 5, including the seafood tower, was included. Not sure about in suite specialty dining.
You will be contacted 15 to 30 days pre cruise on average by the shoreside concierge. They will make all your specialty dining reservations. Your butler can change them once on board.
Yes you can get oj and the new room service menu includes wine and champagne so no problem there. You will also have 2 bottles of spirits of your choice, or wine/champagne in your suite. Arranged through the shore side concierge.
