Hi All - My and my wife are Newbies to Cruising! We are booked on Splendour of The Seas Arabian Sea 7 Days Cruise on 4th January 16. We booked My Time Dining because we just want to please ourselves and go formal if we want! Don't if we want! However its my 65th whilst we are on board and I wanted to book a speciality Restaurant that night. I waited patiently for the Dining section of My Cruise Planner to start taking reservations and logged into my booking etc no problem But when I go into Dining & Beverages - Dining >> I'm only being given the My Time option in the MDR - See Attached image. Can anyone help please!
