Current solution is wrong, it should be "Have you vocationed somewhere in the East?", that's how native English speakers say that.
'Have you been on vacation somewhere in the East' should be accepted.
Yo, this HAS to be changed to "Have you rested(vacationed) anywhere in the east?"
What is "the East"? The Far East like Japan and Korea, or the Middle East, or just Eastern Europe like Russia?
