If you are in water right underneath the moon and the moon is at it's closest, do you float better than other places on earth?

Nope! The Moon is pulling both you and the water equally, so it makes no difference to how you float.

Tides work because gravity drops off with distance. The near-side of the Earth is pulled by the Moon more than the far side. So the water tends to be pulled away from the middle, and piles up on the near side, and falls away to the far side (edit: just to repeat, that's *to* the far side, ie there are high tides on both opposite ends) - although the exact level of this and the timing of this depends a lot on the local geography. Over thousands of kilometres the difference in the Moon's gravity is big enough that there's a net difference in force, and that makes the water flow.

But if you're *in* the water, you and the water are in pretty much the same place, feeling pretty much the same force. So you don't really experience any extra force relative to the water.
