Are the tools on the job, be hard getting the tools over on a tourist visa, and is it cash in hand every week, it sounds good nice break from the norm.
I do that run quite a bit and I don't get jet lag going west 4 hours time difference, it's coming back east that it's worse but nothing special. Certainly wouldn't lose 2 days to it. Get a morning flight that gets you in dinner/early evening time and start the next day.
i would be more concerned about getting my tools over specially as there are large format tiles involved
It's the 'experience'!
It must be fantastic to see the Manhattan skyline from a bathroom window.
Taste a real Big Mac.
I'am looking forward to more details when Paul gets back from Qatar.
