Thank you very much for your comments. It is not their first cruise but they were really scared by the loud noise of banging and shouting that has awakened them. We have talked to them, explaining what was happening, but indeed, HAL should have informed us beforehand or really should have compensated the kids by sending them some treats for the « inconvenience » (as the supervisor of the Front Desk addressed the whole situation). It might sound as a First World Problem, but if you are on holiday, than you want to offer the best experience for your kids and not return home with some bad memories. The whole management of the issue is what bothers me. We cruised HAL several times before, but clearly never experienced the handling of issues in such a manner.
