Diamond Members do have different lounge to the Concierge Lounge, it varies from ship to ship and can vary from cruise to cruise depending on the amount of Diamonds onboard. As for allowing others in who are not members, no chance. As for the loyalty functions, they are the same as every other line, free drinks, a dance band and the usual 'Welcome Back' from the Captain...........Wilba.
So you think two adults (or as you put it 'kids') should be allowed to enjoy these extra facilities which are not covered by the grade of suite they have?
I think I'll see if I can get my two mates in CL too. They have booked an inside but surely 'once or twice' will be okay won't it? Why shouldn't we all get what we don't pay for?
Draconian? Yeah right.
Think of it the other way around if it was Cunard ,would you like someone bringing in there friends/family for the odd occasion...I have a feeling you will find RCI very different to Cunard..Good Luck.
