(I think)

So yeah.. if you can somehow create an (almost) air-tight lid for the hot tub, siphoning won't work, just get a bucket or tip it over if you can.

Siphoning would definitely work. I just did it to empty my fish tank. Sucking in through the tube pulls water through it, when it starts going through the other end it creates a vacuum which sucks the water into the tube to fill up the empty space. You don't need any kind of equal pressure, just a tube. Then all you have to do is create a simple vacuum.
