How much to charge for hotel photography?

You should try to calculate a day rate for yourself to answer these questions. Take how much you want to make per year. Divide that by how many days you're planning on working. Does it seem feasible to charge that amount? If not, reassess how much you want to make per year. That would be the top-down approach to pricing.

If you want to build from the bottom-up, try to figure out how many hours total you will spend on site, in post-processing, traveling, and engaging in various administrative or financial tasks. Multiply that by a dollar value that seems reasonable to you. What's the total?

In the end, since you're providing a time-based service, it's next to impossible for anyone to give you an estimate without an idea of the scope of work you're supposed to provide. Are you taking five photos of a small hotel? Is it a multi-day affair with a large amount of hero shots that will be used for international marketing efforts?

That all being said, here's a hypothetical that may help you.

If you were to be in a major metropolitan area in the United States shooting a small campaign for a reasonably upscale hotel/club with a total of 4 hours on-site, 8 hours of post and 2 hours of admin/travel, I would charge somewhere around $3-4k with a perpetual use license for digital, print, and internal use. This would be based on a small number of hero shots (5 or less) along with a group of various shots and vignettes totaling less than 50 finished photos all together.
