Denied again for otel.com (membership). I was also denied olotels.com because of this in their T&Cs:
h) – Currency rates displayed on our website are not verified or guaranteed by Olotels as being accurate and should be used as guidelines only. Rates are not updated every day and actual rates may vary.
The agent suggested this meant you could book a rate that wasn't guaranteed and could change. To me, the clause suggests that non-USD rates (as it's a US website) are a guide only but the agent wasn't interested in listening.
On the upside I was successful with hoteltravel.com for a Park property that saved me almost 50%.
