I would also only stay at the Fontaine for one night -- doesn't really make sense spending multiple nights there. In other circumstances, I would stay in Shinagawa -- I would say it adds 30 minutes to your trip to the check-in counter, but you would be in the city with all the associated accoutrements. Plus I think the Prince is usually cheaper.
The rate I paid didn't come with anything (I'm not sure about onsen entrance - that's normally 4,000 yen, but I wasn't planning on using it so didn't ask).
I agree the Villa Fontaine Haneda is best for one-night stays. And very convenient if you have an early flight out of T3 or a very late arrival into T3.

The onsen is quite good, open late. Top floor, part inside, part outside on the roof. Closed 1.30 am to 5 am for cleaning. (Until this summer it was open in the early hours of the morning so this is a change). Hotel discounted guest rate is 2000 and there is onsen clothing in the room you can wear.
There are many restaurants and a Lawson in the shopping as you reach the hotel entrance area. I would not bother with the hotel restaurant. If you walk back to T3 there are loads of moderately priced restaurants on the upper levels landside.
Be careful when booking this hotel, some booking platforms offer a bewildering choice of packages based on room size, breakfast, onsen ticket and checkout times, either 9 am or 11 am. The hotel will charge you an hourly rate if you check out late. You check in with a kiosk and the card keys will only work until your reserved checkout time. Rooms are not as small as a Japanese business hotel but they are on the tight side. Not much of a working desk either time I stayed there which is the biggest drawback for me. If you cannot read Japanese or some kanji ask for the wifi instructions before you take the lift to your room. You connect through your TV which was set to Japanese as a default both times for me.
The hotel is not a bargain but it is clean, new, and adequate for its purpose- super convenient to T3 for one-night stays. Otherwise there are far better choices in Tokyo or Yokohama.
