Terrible Bellboys, Terrible beds, Unresponsive re Suggestions
When we arrived, five bellboys surrounded us at the trunk. We said we would handle our own bags, thank you. They grabbed 2, I stopped them. They grabbed the 3rd. I told them to stop. I suggested to the hotel security that that was a very bad practice. Our bed had posts lower than the mattress - yes, we bumped our legs into them several times. Ouch.
The sheets were not fitted so came loose all the time - very unsanitary. We had to call to get maid service every day. The hotel was very full but....that is no excuse.
The other groups held their meetings between the elevators and escalators - high traffic areas - and the hotel did nothing about this. 
I let the front desk know and she didn't care. 
As we were leaving, 10 bell boys tried to grab our bags. We told them to not touch a thing. Each in succession asked us if we wanted a taxi. We said no we had a car waiting. Did they have a car waiting for us - and gave them our name. 
The answer was no. And no, those cars belonged to the hotel.
After a half hour, we called the car service. He had been there for 45 minutes in the hotel car line. We spoke to the head guy who had all sorts of excuses. We just barely made our airplane. We called the manager to make suggestions. He heard us, and said he'd call back after he spoke to the people. We're still waiting.....Not holding our breath.
The event we attended is using a different hotel next year. Thank goodness.
