If it's really easy. then it's worth doing . In my case, I thought it may be useful regarding paperwork as we have 2 kids.
However, having got all the paperwork in order with the aumper. was directed to the Ministry of Foreign affairs , to get photocopies of passport endorsed. who then directed me to my embassy in Bangkok to get my passport certified as genuine,
So I haven't got one. as for me it's just not worth the effort !
