I worked FIFO in Qatar back in 1988 before they had bars in hotels. Expats with a residence permit could get a liquor licence with a monthly allowance.
Expats live mostly in compounds in and around Doha in European style villas. Temperatures in Summer reach into the 40s with high humidity due to the Gulf.
Since the discovery of one of the world's biggest gas deposits the Qataries have gone crazy and built huge concrete shopping malls and buildings copying the Dubai style.
Restaurants and shopping are no problems with just about anything you want supplied. You will be spoiled for choice.
Don't know how prices are these days but groceries were more expensive for western types than here.
The Qatar people are quite hospitable and fairly easy to get on with.
If you ended up housed in one of the compounds you would live extremely well with swimming pools and sporting facilities. Most expat families hire a housemaid and gardener from either India or Philipines. In the privacy of a compound there are no dress restrictions for women so they can laze the time away lying round the pool while the maid cleans the house.
I have worked in Qatar, Kuwait, Saudi, UAE and Oman and Qatar used to be one of more liberal Arab Countries.
BTW drinking in hotels is very expensive If Dubai is an example.. Back then we went to a private villa in the middle of nowhere the liquorl store run by Cable and Wireless to get our supplies. If you have a liquor licence then everything is cheap as duty free.
