I've only stayed at PVI. While not "designer" (I kind of wonder who came up with the color schemes in the 2-room suite, for example), not all the rooms are as bad as others, if that makes sense. The room I stayed in while I was there in Feb was done in creams and browns, and was very nice. The suite we stayed in last time, though (2 years ago) was one of their "updated" ones, and it was a southwestern palate, but with green marble added in (??). In fact, it's on their scrolling pictures on their website. Again, not "ugly" per se, just not my preferred color palate! I think the Jacuzzi suite was cream colored walls with green carpet, maybe, but that's been 2 years ago as well.
3 years ago, a frequent DISboarder had an unfortunate incident with bed bugs and lack of response from management, which has turned some people off from PVI. I have stayed there numerous times (next visit this month will be #4), and have had courteous staff, clean rooms, and no signs of bedbugs.
My generally favorite things about PVI are: comfy beds (soft, but not so soft that I sink too much), comfy pillows (they smoosh down easily for DH's flat-pillow preference), adequate towels (fluffy, white, will cover my plus-sized booty), breakfast (love having hot breakfasts in the morning, and they have to-go cups for coffee and tea), the secluded-feeling pool area (the plants around it make it not as obvious that you are in the middle of a parking lot, however, I believe Carousel has a roof-top pool, which would be even nicer!), and the staff's helpfulness (opened our room for us when I realized after checking out that I didn't have my engagement ring on, and then they helped search for it, they have charged different cards for certain nights of our stay when my dad wanted to pay a night of our honeymoon, etc). The first night of each stay I've had there they have called to make sure I have everything I need. Floors could stand to be a little cleaner maybe in the Jacuzzi suite, but, honestly, we figured that room probably isn't rented as often, so it's not cleaned as often.
For silly things I like, there's a 10 or 15% discount at Cold Stone Creamery when you stay at PVI, and I love grabbing an ice cream on my way back to the room! And you can't get any closer to the pedestrian entrance!
