Not sure that Hilton actually owns the property about which you speak. Your heading is a bit of a misnomer. Hilton Corporation in LA owns very few properties. It does, however, have management contracts with hundreds of properties across the US. I believe it owns a couple of key Hilton properties in the USA like the Waldorf Astoria, but otherwise it only owns the Conrad properties located outside the USA. Hiltons outside the USA are managed by the Ladbrooke Corporation in the UK, which has owned a number of properties [The Drake in Chicago] but likewise is not in the real estate business.

So to answer your question, I would put The Drake, the Waldorff Astoria, and then all the Conrads. Otherwise, not many properties are owned by either Hilton group.
