Hi,
1. Do you want to remove Room Types in hotel page? If yes, please replace /single-hotel.php in theme directory with attachted file.
And to hide "View on Map" button and "Advanced search" in hoetel search page, please use custom css code in theme options panel. http://prntscr.com/ldsf82
.btn_map{ display: none !important; }
#modify_search{ diplay: none !important; }
2. I can find "View Cart" string in language file in CityTours theme. So you can translate it. And I can not find "Load more" string in our theme. Can you send me page url, so that I can check?
3. Please use following css code.
body.post-type-archive-hotel .container .col-lg-9.col-md-8 #tools .row .col-md-3.col-sm-3.col-xs-6:nth-child(2) .styled-select-filters { display: none; }
