Not enough information to provide a distinct recommendation. This all depends on your career preferences.
Do you want to make a lot of money? What are you good at? Do you want to start your own business someday or just work for the man? What are you goals?
The only thing I gathered from your post was that you don't want to be around people but still want to make a lot of money. I'm going to be the first to tell you that you are in for a rude awakening if that's your mindset.
Here are some generic recommendations:
-Want to have a high earning potential but don't want to be an entrepreneur? Go into sales. (oh no, you'll be around people!)
-Want to learn a valuable skill that can translate to your own future business but don't care about making a lot of money right off the bat? Go into digital marketing. (oh no, you have to know people inside out!)
-Want to be your own boss someday and make a decent living, but not rolling in the dough? Learn a trade, put a few years in then branch off into being an independent contractor. (oh no, you have to deal with people!)
-Mostly concerned about career satisfaction? Review your strengths and interests and pick a career that aligns with those the most. Warning: It probably won't make you a lot of money unless you're extremely interested in programming or other specialized tech fields. I am going to assume you're not if you work in a hotel.

Most of them are shit but this is the best one I've ever taken. It was extremely accurate based on my own results.
The reality is, if you don't want a job "around people" you are not going to make a lot of money unless you choose a highly specialized technology field like programming or big data. Even then, you have to interact with stakeholders or managers. Even a tradesman has to deal with people, especially if you want to make good money.
Barring certain rare exceptions (which you likely would have to work for years to gain the skills to be even employable), there is no such thing as making a lot of money but not being around people, because people are everywhere and they have the money.
Good luck
