Also, if you see a really good rate on something like Expedia but would prefer to book directly with the hotel, call the Anabella directly. They will match any rate that is cheaper than their direct one. They will check it out to make sure that rate does exist!
I did that recently, the rate on Expedia was about $60 less a night for their MIssion Suite. They matched it. Then I ended up cancelling and going over the Hojo. But I though that was nice. The Carousel being a sister property might do the same thing.
I have stayed at BWPPI, the room was very nice ( we had a mini suite). It was spacious, very clean and we could see the fireworks from right outside our door. However, the pool was lame, very small and they don't allow you to take things from their free breakfast area to your room which sort of annoyed me. However, the staff was nice, the room again, was clean and looked very updated and the location was perfect. The location of the BWPPI and the Carousel cannot be beat. The Carousel has had some bad press around here lately and one other issue that may or may not matter to you, it doesn't have a hot tub.
