The one most known for hourly/half day/day use is the "Mingle At The Eden". I have no experience with it, but bros here used it before and seemed very nice and clean (also looking from the pictures not bad).
You can also try the site "Day use". It's not intended specifacally for punting but they offer a lot of hotels in HK, even 4* and 5* for a fraction of the rate what it normally costs to stay there 24h.
