Hi there, Europe is a large area with diverse cultures, which region are you thinking of? which countries are you planning on visiting? where will you be flying into & crusing from?
For other children, there may be a few depending on the week, as a lot of Europe have 'half term' breaks from school in the first week.
If you choose the Med, then your seven year old may be compensated for the culture & architecture with decent weather, but if you are thinking of the Baltics, or Fjords, then you have a greater risk of cold, wet & dark days.
If you provide more info on your plans, then we will try to help where we can.
