We've only stayed at the Park Place Inn, but that's the one I'd go with.
As everyone else has said, it's RIGHT at the crosswalk. That alone would make it the one I would choose.
It's clean, it's comforable. The minisuites have 2 queens and a sofa that can fold out. There's also a fridge and a microwave, and the fridge is pretty good sized (not the little cube one). The free breakfast isn't the best free breakfast I've ever had, but it's better than many of the others offered on Harbor.
If you don't need the sofabed, the couch is part of a sitting area, with a coffee table and an additional chair. There's also a desk and an office chair. It was great for snacking or eating breakfast in the room, and it was so nice to be able to sit somewhere other than the bed.
We were very happy with our stay there, and it is for sure our go-to motel at DL now!
