I can't see why not. Have them in your carry on luggage and declare them to security on arrival. (If you put them in your checked bags you might end up called to the naughty room to unpack). Security take loads of stuff off folk on embarkation - irons etc - I can't see why they can't store your alcohol for you!

Yes all the time. DD was home educated so we never paid the inflated holiday time prices. There are fewer children but still plenty to do. DD always found friends. ETA - She has only cruised Celebrity. Wouldn't set foot on a "kid" type cruise!

In suite dining from the restaurants is only available in upper suites. You can order from the room service menu.

All cabins get something. Concierge etc get the lightweight not quite re-useable not quite disposable one. Aqua get a draw string spa bag thingy and suites get the more robust one. It is a bit hit and miss (suites) if you get the zipped one with the internal pouch which is blue or the non zipped grey one. Exactly when they turn up is also something of a guessing game - sometimes in the room on arrival, sometimes on the bed at turn down before the first port, sometimes on the bed at turndown on the firsl chic. If you haven't got one and want one just ask - although it may be lurking in a drawer somewhere!
