There seem to be a lot of "new" staff members both in the hotels I have syated in and the lounges in Siagon. It may be a traning issue. Just had a short non accor at Hoi An ( town spoilt by day trip coach tours ), where the hotel we stayed in was traning 3 new members of staff. They were in the end process of traaning. All had done over four months so far, and had probbly two more to do before they could join the "teaam". However there also seemed to be a lor of penny pincing in the Accor Hotels ( Hotel des Arts especialy )
