With premium plus, we always ordered a bottle of the premium sparkling wine at the beginning of dinner. The options were Moet or Nicolas Feuillatte Rose last time we cruised, pre-COVID. Since you'll be the only one drinking it, you can have a glass and then order a different wine by the glass with your dinner. Staying in the Haven, your butler will deliver the bottle with the remaining wine to your room. Voila - balcony wine!
