It only counts as disposable income if I can take it back when I go home. Otherwise it's just more cash in the sheikh's dish dash.
If I take the allowance and save some then it's disposable, if I pay off a mortgage at home while the sheikhs pay for accom then it's disposable, if I buy a house/villa and I achieve capital gain or I pay off the mortgage and recover my deposit and the allowance then it's disposable income.
Otherwise if I am given a place to stay while I stay as a guest in these parts then it makes no difference to my bottom line.
