A simple calculation USD 80,000/26 days gives you ~USD 3,075/night.
What hotels and what rooms types are they staying at? Assuming entry/mid-level suites, you'd be looking at ~USD 800-1,500/night or thereabouts (and some of these - e.g. Aman-i-Khas - come full-board). A mid- to upper-level suite you're probably looking at ~USD 2,000-2,500/night which would seem fair accounting for the difference if there are added things in the itinerary (flights, car + driver, train, excursions, meal plans etc).
Maybe you could lay out the full journey as it would be difficult to gauge otherwise, but if entry level rooms, it does seem excessive.
