Update - I called Dolphin again to see if the problem had been fixed (PL never contacted me), they tried every name, number, date and could not find the reservation. The agent asked if I was calling about our previous reservation which is c/o already - I am baffled since I have never stayed there and my name is super unusual.
So I call PL again and the agent told me that she can see how the previous agent had escalated the issue but basically nothing has been done yet. She said they need to call their "sister company" which is who books reservations with S&D. I asked who they are and she said Tourico - ugh! From working fd at a hotel I know Tourico. They are a pain, so is their parent company HotelBeds. Rates are always wrong, wrong dates, reservations go missing. The agent kept saying that there is no problem and my reservation is confirmed - yeah, they already charged my card so it better be confirmed
The Dolphin agent did say that she is pretty sure she sees my reservations but for security reasons could not give me the name they are under - I am thinking maybe they were booked under the wrong name (?), not by me or PL (my confirmation email has the correct info) but by Tourico.
I am just so glad we are not going until next year or I would be super stressed. As it is I have plenty of time to call every day if necessary to get this fixed.
