Yes, Hotels Plus is clearly a scam. I made a reservation, paid in advance, and received an email (supposedly from the hotel) cancelling my reservation a month later. Hotels Plus called and said they would send an email in 48 hours saying when my refund would be processed. I waited a week and never received the email. I called and they said they had many cancellations, so it was taking a while to process them, but mine would be handled that same day. It never was.
