Asking questions about cruise tourism in Europe

At that time, the weather in Europe was still relatively warm. In addition, the weather was fine in previous years. On sunny days, you can usually wear long sleeves and a jacket. In France, it is recommended to take a sweater to prevent the weather from changing and the temperature difference between morning and evening. In short, clothes are mainly in spring and autumn, and clothes for late winter and early spring and late spring and early summer are prepared. But I don't know whether your cruise is mainly on the cruise ship or on the destination ground, because my understanding is that you are actually on the ship most of the time. The ship has central air conditioning, but it won't be too cold, but it can't stay in the cabin all the time. It will still be cold to blow the sea breeze on the deck or something. Be sure to prepare a thick coat like a strong jacket.
