I stayed at PH for four nights at the end of November. I arrived in the early afternoon, had to wait a few minutes for a desk clerk (they do have separate check-in for Total Rewards Diamond and above.) The registration area is on a separate lobby floor below the casino level, which means you never have to drag your luggage trhough the casino. The clerk was polite and efficient; I was not offered any kind of upgrade, I had reserved a standard room with two queen beds. The room they gave me was on the 20th floor and faced east with a view of the Platinum hotel, PH Towers and the mountains - I did not care about the view so that was OK. This particular room was also right near the south elevator bank which was very convenient.
Before arriving I had read some very good and very bad reviews of PH, but I found the property to be quite ordinary in most ways. The room was large but poorly laid out so a lot of the square footage is wasted in the entryway. The desk and chair were crammed between one bed and the wall with no space in between. Some reviews had mentioned finding the room to be dark because there was no overhead lighting except in the entryway; this was true and exacerbated by the dark wood furnishings, but there was enough light in the areas where it was needed - desk, nightstand, floorlamp. The carpet and wallpaper were pretty ugly. There was an older model flat screen TV with a surprisingly good choice of cable TV channels by Vegas standards. The bed itself was a little softer than what I'm used to (I like a firm mattress) but I slept OK on it. There were two kinds of pillows, normal ones and softer ones that were lumpy - maybe filled with buckwheat? I preferred the regular ones. The window was not large but not tiny either.
The bathroom was good-sized for one person. In fact, there would have been room for an extra sink if the soaking tub hadn't been in the way. The bathroom doors do not lock and there is a crack in the center that can be seen through; however there is a separate toilet cubicle which offers some privacy. Separate shower stall. Shower temperature and pressure were pretty good, and the shower head wasn't too low as I've experienced at some other properties.
I did not have any problem with noise from the hallway or adjacent rooms. You could hear the hot water pipes when someone was taking a shower upstairs but that was about it.
At PH the big gimmick is the genuine Hollywood movie memorabilia used ot decorate your room. I got the "El Cid" room, which contained a costume, props and movie posters from the movie. It seems to me that PH is missing a big opportunity here. I found the decor mildly interesting, but if it had been one of my favorite movies I would have been jumping up and down. They ought to note this in the rooms database so that when you check in they can say, "Would you like the "Rebel Without a Cause" room, or for $20/night we can upgrade you to the "Some Like It Hot" suite?
The best part about staying at Planet Hollywood was being able to grab a quick bite at Earl of Sandwich or Pink's hot dogs and bring it back up to your room - so many properties the only casual food option is the food court.. Otherwise, it was really pretty ordinary. I've stayed in better and worse. I would not refuse to stay there again but neither would it be my first choice.
