You really should do some research before joining an airline , especially if you take children with you.
However , I like to help , so I can tell you that you will most likely have to pay a bit extra over your rent allowance , but you should get yourselves a very nice villa for that .
There are 700s and 800s ( more coming ) , and MOST of the flying is out of Oman , several nightstops .
Enjoy.
