Doubletree by Hilton Hotels in San Pedro

I was booked a King size bed when the web page turned up. I have booked 4 nights before this. I asked Alexandra to update my booking and extended the same room for another night. She said it’s fine and our room cards extended. Unfortunately, when I double checked with Luis, Mexican staff in the morning of 1 November 2024. He said that I have booked a Queen size and it was unlikely we could get the same for the last night. He added that we had to change to a queen bed room. We were preparing to go to downtown right now for the Dodger Parade.  We had to pack our luggage in a hurry and move to a higher level room. It didn’t give a us a good start of our day at all. My question is: why did Alexandra not telling me that we were not going to have the same room when I talked to her  about extension of another night? Or, we did get the same room but Luis did not follow and made us a hard time? Please investigate and improve the service in future!
