I noticed that the Princess Acapulco took 2 certs from my profile and 4 days later, I still have yet to receive a folio showing the transactions and certs exchange rate.
According to Oanda today, I should get 370 MXN per 25 USD certificate. With the terrible service at the property, I would not be suprised if they screw me on the exchange rate. That would be icing on the cake with them.
I will post the update when I find out as a datapoint.
