We stay at BWPPI because the room size works well for our family, we do the BW Rewards program, and it's location is great. But as the previous poster said, it's just a motel, and very similar to other motels we've stayed at on Harbor. The room size and price work for us, so that's where we stay, but if they were booked on my dates I'd just choose something else, not a big deal.
I've never stayed at Carousel, so I can't help you there. I'm sure whatever you choose will work out fine.
