I'll be travelling to Busan for 7 nights staying in the Ibis City Centre. I need to visit Osaka for 1 day & rather than come back the same day, I'd prefer to overnight there. I'd rather not have the hassle of packing up, checking out & rechecking in at the hotel in Busan so, what would be the implications of staying in two hotels at the same time re: points & status nights? I'll need the 7 nights in Busan to retain my Gold status for the following year so, whilst I'd prefer to use an Accor hotel in Osaka, I don't want to jeopardize those status nights.

Does anyone have experience of a similar scenario as described above?
