Lexsea,
Is your niece a social butterly or is she shy? I would guess she would just need to hit it off with another girl near her age and then you won't be able to keep her out of there!
Sounds like you will have a great all-girl's trip! I might have to look you up to get away from all the men I an cruising with- DH, DS15 and his friend, who is also 15.
Welcome to the thread. Only 7 weeks from tomorrow - that must mean 50 days to go - and counting!!
