We had considered it but didn't. It was 11 days in Dubai, including some school days.
I know some people that have.
How old is your child and what was/is their rating? My son just got invited by the local chess coach to take weekly lessons from him for free if he wanted to pursue qualifying for the 2015 world championships in Greece. We would have never considered anything like this, but 2 hours of lessons a week for free is a pretty incredible opportunity for us and it is pretty amazing that the coach thinks this highly of our son. We homeschool so the time gone would not be as big of an issue for us, though the expenses certainly would be. Plus I have no idea if my son can raise his points enough in time for the qualification cutoff, though he has raised it more in that amount of time before. Currently he is #9 in the U.S. for his age, #2 in Texas for his age, #65 in the U.S. for ages 7 & Under, with a 1186 rating. So not WAY high, but decent.
