A recent poster said that the Conrad Tokyo and Conrad Singapore were their favorites and I'd concur. These are definitely my two favorite Hilton family properties with Tokyo my absolute favorite. As far as Hiltons, I'd choose the brand new Hilton Queenstown (NZ) as my new favorite. Admitedly the place was not very heavily occupied when we stayed there a few weeks ago during the first week of its soft opening (we didn't even know of its existence until the staff at the Hilton Auckland mentioned its opening to us during our vacation in NZ). But, everyone on staff from the GM, to the concierges, to the front desk staff were amazing. And, the Wakatipu Grill was outstanding. Brian Campbell, the pastry chef, is really outstanding.
