the great attractor

Yes, but does that make a difference?

Remember, there are tides on both sides of the Earth. There's a high tide directly below the moon, and another high tide on the opposite side of the Earth from the moon.

If we are just talking about one location the gravitational pulls of the sun and moon sum up to less when they do not pull in the same direction.

I notice this on the tide chart

where I can see that the highest high tides occur when the moon is New and not so much (but still pretty high) when the moon is Full


I assume the same pattern plays out in other locations around the globe.

Sorry, different to when the Moon is orthogonal (90 degrees) to the Sun. I was trying to clarify confusion I perceived in George's post.

Full Moon and New Moon aren't significantly different.

as/re the great attractor
We do not know what it is, nor if it even exists as we might have imagined it
Here is a take on the subject from phys.org
https://phys.org/news/2016-05-great-attractor-milky.html

OK
If it does exist as we understand it, then it must be really massive to hurtle the milky way at 2.2-million kilometres an hour
wow
ok
if gravity is pulling us toward the great attractor
then
is the great attractor being pulled toward us?

It is almost certainly a galactic supercluster.

If it does exist as we understand it, then it must be really massive to hurtle the milky way at 2.2-million kilometres an hour

It's had a LONG time to accelerate to that speed.

Of course.

Just like the Earth is attracted to Newton's falling apple.

BTW, the Great Attractor itself is being drawn towards an even more massive object - the Shapley Supercluster.
