I live in Abu Dhabi and know quote a few people who've lived in Oman.
i came over with mife and kids and it can be stressful moving and settling with family but the same could be said of a move to any other country.
Fro what I've been told, the locals are very friendly, there's a slower pace of life in comparison to the UAE,
some stunning scnery and is a real hub for family camping holidays it seems.
Heard mixed reports on Muscat, not a lively city but it's very safe for families but wouldn't have the glitz of Dubai if that's your thing - I wouldn't care about that.
Another thing worth knowing is there's a city/region in the south of the country where the temperature doesn't get past the high 20's called Salalah which
has lots of beautiful scenerey with rich vegitation and greenery which you might crave due to living surrounded by desert!
You're also in a great spot to exlpore regions/countries near to you. I tend to save every penny but mates have been to Napal, Goa, Petra, Sri Lanka and other such places.
