I am holding elite status in both IC and Marriott. I,ve booked myself for both hotels in Sydney next month. Both have already confirmed upgrade of my room to a harbour view suite room. The only difference is Marriott grants free access to the Concierge lounge whereas in IC I have to pay a supplement for it. Any suggestions on advice on which one to chose? IC looks more opulent but the supplement is quite alot- 150 $ per night. Any advice would be appreciated.
