I don't have personal experience with any of these, but I just did a bit of research, and the 2 I've bolded (I think the second one starts with a W btw) appear tolerable (at least compared to the other 3). Basically, if you have a true overnight layover in either direction, I would definitely pass on the free hotel, and find somewhere else (BJ hotel rates are not especially expensive). But, in your case, a hotel near the airport could be useful simply as a place to drop off your stuff in the morning and wash up in the evening before your onward flight. By the way, unless they make the hotel shuttle super easy (i.e. someone from the hotel is waiting for you with a sign), I'd probably just grab a taxi. Some drivers might act angry about the short ride, but they get a queue jumping coupon whenever they accept short rides, so this isn't a big deal.
