Some other suggestions, although not necessary - Travel pillow, chewing gum (especially for those who have ear problems during flight), book and/or ipod and one change of clothing (air lines do lose luggage occasionally)
My advice would be to do as many excursions as you can. They are a great way to get to know your group, and they are always good fun.
One of the most amazing places in the world! Best thing to do - GET LOST!
