In some locations, $100 would be an extremely low rate even for a HP/HH.

Some places that can be very reasonable for the location and hotel would seem to include GH Rio Barra (Brazil), PH Mendoza (Argentina), GH ICN (South Korea), HR Tokyo, HR TST (Hong Kong), most Hyatts in smaller cities in mainland China, and even (relatively speaking) PHT (Japan) for a Glob if you pick dates when the hotel isn't very full.
