Hotel Charges that are in Dollars

Quotation-->
"I have continued to find that MOST of the Hotels in Zihua whether small or more expensive are charging in dollars and have been for years. I'm not familiar with Ixtapa so I don't know what they do. I don't know any other country that does this or maybe it's just individual hotels, towns. Any thoughts or suggestions? For example La Quinta de Don Andres. While we will do whatever, just seems odd that this continues whether the Peso is low or high."

In Bungalows Adelamar (near La Quinta de D. Andres) in the La Madera, el encargado Roberto Campos quoted me in US$ when I went there personally to get rates.
However, I told him that IF my visitors decided to stay there, we will ONLY pay in MX PESOS.
So, he came up with a quote of $1,200.00 m.n. per night, (which beat his original Dollar quotation), and comes out to be around US$62.00, more or less, at current x-rate. IMO, quite reasonable.
BTW, That quote was for the 2nd - 3rd week of this month, December 2016.
