Hi
Good to see your message.
I'm on the same holiday, but flying from Bristol.
There is another posting about this holiday, on this forum, see :-

From other JY holidays I've been on "smart casual" is normal for evening meals, although often people dress up a more on Christmas Day. Just do what you feel comfortable with.
I would hope it's reasonably warm, like a UK summer.
There will always be a delay before your posts appears, because the forum is moderated, and posts have to be cleared to cut out spam etc. This is normally only a few hours, but is longer at weekends, as Julia needs some time off !
Look forward to meeting you.
Stuart
