Ah was visiting for the first time. I stayed at the Canopy Hilton and a Room with a View (3 different rooms there). 3 out of four rooms I stayed in were new to new-ish looking; didn't use hot water from the ground. The last one at a Room with a View was very old from the old style elevator (all other rooms used more modern /present day elevator) to the older building (hallways) to the room making me assume since the newer rooms didn't use natural hot water that only older places do.
