Location in ocean furthest from any land. Are there any established organized travel options for a tourist?

As far as I know the point in the world's oceans furthest from any land is located in the Southern Pacific, roughly halfway on a direct line from the Marquesas Islands (French Polynesia) in the west and the Galapagos in the east.

It's a bit over 2500 km to these island groups and about the same to Easter Island (south), Socorro Island (north) and Pitcairn (south-west).
(If I'm wrong and there is a more remote spot in the oceans, feel free to edit the above. Question remains the same.)

Is there any possibility for a tourist to get there by some form of organized travel, that runs on a more or less regular basis? (Either by ship or a fly-by.)

This is to satisfy the curiosity of me and some friends. This started with "Name any place of interest in the world and there will be a travel agency organizing regular trips to it, so people can go there for bragging rights".
So far, we haven't been able to find a travel agency organizing travel to this particular spot.

To further clarify:
We are looking for a travel agency that offers this as (part of) a bookable, standard trip, and has made the trip at least once before. (Otherwise, with enough money, someone can always pay a travel agency to organize a one-off trip. That doesn't count.)
It is fine if these trips are are not on a regular schedule and are on demand only.
We are ok with any trip that includes this spot in the itinerary, but doesn't have it as the main goal. (I can imagine some cruise ship will pass it going from the Galapagos to French Polynesia.)
