Disappointed
I had a disheartening check-in experience as an Omni Black Select Guest member the weekend of May 4-6. I was attending a wedding in Houston and flying out to Orlando on business after. 
In addition, the air conditioning unit in our room was not working the first night. After calling downstairs around midnight, a maintenance technician came up to check the system and told us that the water pump had been turned off. Who turns off a water pump when the room is used regularly? 
After calling downstairs the next morning, we were told that the air conditioning unit throughout the hotel had recently been upgraded. The front desk manager was very nice and upgraded us to the Presidential Suite bedroom. Again the air conditioning worked poorly and we noted that the entire hotel - lobby, hallways - was extremely warm. 
I was sweaty the entire lenght of my stay on the property and opted for checking out early to seek refuge at a restaurant until my flight later that early evening. The air conditiong in my vehicle was preferred to the air conditioning on the property and even a maid made a comment as we were leaving our room and I was fanning myself about how hot the building was. 
Overall - the stay was frustrating and disappointing.
