But i am still sure that even breaking out of words in my domain it will not lead to any explicit word
Don't worry, Google gets it. If you use terms in the pages (for the example) like "reservations", "room service" or "checkout time" then they will know you're a hotel website.
Still not able to get this, Fetch as Googlebot is in our hand we can use it to fetch and submit to index
Some people use that tool to double check that their ad and tracking IDs are accurate when they think someone hacked their site. For this thread, all you're doing with that tool is "fetching" a few pages to look at them, not submit them. Beside each "fetched" page listed you should see the "Success" link in the "Fetch Status" column, click that to view the headers and source for the page. Look at the source carefully: Is there anything in that that you do not recognize as coming from your site? You should see if a hacker injects links, text or code into your pages.
