I had a multi-night stay in Del Rio, and I decided to try the Whispering Palms because it had good reviews. It met my needs. The only negative was that the air conditioner was pretty good, but not great. I like it really cold when I sleep, and it didn't quite get there. But I realize I like it colder than most people, and it was comfortable enough, so this was at least as much about my personal preferences as the condition of the A/C.
The staff was very friendly, and the owners were, too! Bob and Joty made sure I was having a good stay, and they've got a great dog who loves to get her ears scratched. There's also a bird named Larry in the lobby who is entertaining.
You can buy water or soft drinks in the lobby, and the proceeds go to an orphanage in Acuna, Mexico, that the owners support. I loved that.
I plan to book this hotel again when I am back in Del Rio. Thanks for a great stay!
