Thank you! Yes i did take good advantage of Qantas fast track and Accor Plus but it will pay off big time! I did see that, not quite sure i'll reach it but there's a chance.
Thank you for the conservative value! At least it gives me a good understanding of what to try aim for. The Pullman in Tokyo was about $300-$350 a night saving, bringing it down to about $400 a night (with the current promo). Though checking again tonight, this price has gone up so thinking it's a bit too far from our usual budget now... haha
I have definitely studied the platinum perks though! We're looking to stay at the Mercure in Tokyo this time round, instead of the Ibis Styles East, so that should be a nice upgrade.
Ah yes, good to know that. We were looking at using them soon but stacking them makes it quite enticing. My Accor Plus renews in November so have to think about it closer to that time, in case we don't use it on this Japan trip.
Was this close to booking Pullman Tokyo, being the only option in Tokyo that allows the use of SNU. Unfortunately with the price up again, will need to reconsider this. It's a struggle choosing between the non-refundable promo and flexible price.
Thank you for your detailed response! I'll be sure to report my experiences in the thread in the coming year/s!
