Thank you all for your comments. I was hoping that you would tell me that Princess no longer advises a Tux/suit/Jacket for men on formal nights on Alaska Cruises as a few other lines have moved away from this recently. Its not that I am against dressing up on formal nights its just that we are travelling from UK and having a few days in Vancouver so would prefer to use our airline luggage allowance for smart/casual clothes. Perhaps we will just avoid the MDR on these nights if we feel a smart shirt and trousers are not dressy enough 🙂
