Which job should I take?

I have two very good job offers.

One is in Abu Dhabi and pays $52000 US with housing, children's private school, health, travel, yearly vacation with plane tickets round trip, return ticket stateside and relocation costs. The position includes a three year contract and I would work 40 hours a week. The cost of living is average or comparable to the US. Abu Dhabi is a desert, but is at the coast. Sports and swimming are available. My husband would be able to get a job if he wanted.

The second is in Majuro in the Republic of the Marshall Islands. It pays $30000 US, health, travel and return ticket stateside, and relocation costs. The position includes a 2 year contract and I would work 20 hours a week. Majuro is an atoll (an island of sorts). Cost of living is high and it is third world country environment. The kids education would cost $6000 a year out of pocket. There is no guarantee that my husband would be able to get a job. Majuro is a tropical island and I do love scuba diving!
