The package doesn't mention education. Schools are expensive (and hard to get into) here. They have long waiting lists for the better schools. Did I mention the better schools are expensive?

Is the ticket annual? Is it just for your or for the family. Good packages offer tickets for everyone every year.

Accomodation? What type of standard of living are you looking for? Apartment, villa, what kind of amenities? More importantly, where will your children be going to school and where is your office? Commuting here is horrible to somewhat bearable depending on where you live and where you need to get to at certain times of day.

Is it private medical and insurance? Better packages offer these.

You need to do a lot more research on what you and your family need to be comfortable (according to your standards).
