My experience in June was quite different. I had a 1 night stay, one night elsewhere, then followed by 3 night (weekend) stay. Each time at check in I was wisked away from the lobby to the executive lounge for checkin and thanked profusely for my business.
The first stay I was booked into a regular room and upgraded to an executive room, given lounge access, and a bottle of wine and box of chocolates as an amenity. On my return one day later I was booked into an executive room and in fact given the same room I was in before! Again, lounge access, wine, and chocolates.
Sorry that you had a poor experience, hopefully they take care of you on your return!
