It's fine if you're staying at the hotel and can get in for free, but I don't think the OP would be happy paying 4200 yen per person just for that experience.
There are plenty of public pools all over Tokyo for a small fraction of that price, though you'll have to put up with silly rules like "everyone out of the pool for 10 minutes every hour, so you can rest and so we can re-check the water quality"

Or you can just hop on the Yokosuka or Shonan Shinjuku line for an hour to Kamakura and swim in the ocean for free.
