I think that is how it goes. You save money by getting the package, the trade off is that you cannot book a restaurant until you get on board for any of the nights, you are however guaranteed whatever restaurant you want on the 1st night. Not sure if you can alter this aspect though
Has anyone ever experienced getting to FCO well before check in time? My flight is for 6:05 pm however my wife and I will be arriving to FCO around 11:30-12 pm and we have 2 bags that need checking in, however check in doesn't start until 3 hours before the flight. Is there any place to store luggage or can the airline (Norwegian) hold onto it somewhere?
