I have travelled quite a bit around the world and the US and this was the WORST experience I have ever had in a hotel. It started with the check-in. I am a Caesars Diamond Member and I went to the check-in reserved for Diamond and Seven Seas members. After standing in line for over 45 minutes and having the staff take 8 Seven Seas members ahead of the lowly Diamond members, I said something and was met with the "Seven Seas members come first, blah, blah, blah." Every other property I have been too, switches back and forth between levels - not this one. At that point, I went to the regular front desk and was checked in within 10 minutes. An hour wasted of my time. The room was nice, but I couldn't help but notice the in-room coffee maker was gone and the wallpaper was peeling by the tub in the bathroom and the STENCH of smoke that met us when we walked in our NON SMOKING room. When I go into any hotel room, I check the closet, the drawers in the nightstands and the dresser. In the nightstand, I found an ashtray with cigarette butts in it, empty cigarette packages and a water bottle of cigarette butts. I threw it in the trash and left the ashtray on the table.That night we went to dinner at Old Homestead Steakhouse and the waiter started talking about CA politics. Not exactly what I wanted to hear when having a romantic dinner with my husband. The next morning, we went to order Room Service for breakfast and found out that they have discontinued room service due to COVID. However, you could order breakfast from one of the restaurants and get dressed and go pick it up. Didn't make any sense to me than and still doesn't. What happened to contactless delivery? We ended up checking out early and going to breakfast before leaving town to head home and that is where it absolutely gets more interesting.A few days after arriving home, I checked my credit card account and found an additional charge of $300 from Caesars on my account. We had already been charged for the incidentals, so I was curious what this charge was for. After several calls to the billing department, I found out it was a smoking in the room charge and a charge for damage done to a bathroom door. We are both NON-SMOKERS, but were being charged for someone else. We are in our late 50s and we didn't even touch the bathroom doors, so now we are being charged a fee for damage and smoking in the room. The front desk manager Evander said the charge stands and that they have pictures. Great. How about sharing them with me or listening to a long standing Diamond member? (It has been disputed with my credit card company).Overall, I will never return to Caesars Palace and am debating about cutting up my Diamond card and going back to MGM and their properties and Caesars can pound sand. Like I said, worst hotel experience I have ever had and I am a frequent traveller.
