Typical standard upgrade were those entry level courtyard suites for Diamonds when it was a Hilton, even Golds got those sometimes.

Very surprised there is no refurb of the "Spa"...its so legacy.
Afternoon tea a step-up, per their standard but no hot food at all, how weird, there was two or three varieties when it was a Hilton.
That Exuberant crap was on offer in the Hilton lounge. Spirits also entry level. I thought IC had top-shelf?
Welcome gift is a big step up, but again a brand standard?

What about the restaurant breakfast? Were you not invited or didn't go cos its legacy?

It will be interesting as time goes on if the higher costs will pay off for the owner in terms of profitability vs the Hilton's lower brand standards and brand recognition.
