There would be a limiting factor, though: how far could Kirk go from the site of discovery of the Botany Bay without arousing Starfleet's interest about strange inconsistencies in Kirk's navigation logs?
The very fact that the Botany Bay remained undiscovered for so long seems to be due to there being no Earth traffic in that vicinity in the recent years. So Kirk's best bet might actually be to leave Khan on a planet very close to the site of discovery, trusting that no Earth traffic would spring up in the near future, either. And of course, the less time the dangerous supermen would spend aboard, the better!
Alas, Starfleet would be aware of the traffic issue, too, and would thus think it an excellent idea to place their secret Genesis development facility in the neighborhood...
So basically, both Ceti Alpha and Regula would still be out in the sticks in terms of traffic, and probably far enough so that subspace telescopes and the like wouldn't spot any planetary explosions or DDM activity or whatever. But they'd still be rather close to Earth in terms of lightyears, allowing Kirk's training cruise to reach them rather quickly.
Also, it would indeed be plausible that Kirk's ship would be the nearest Starfleet asset in this area that was almost devoid of Federation traffic. She need not be the only one in the entire universe this time: there could be a dozen other starships just a few hours farther away, but Starfleet wouldn't consider sending any of them in for what looked like a simple communications problem or a bureaucratic mix-up, one that personally involved the VIP guest of the Enterprise to boot.
