Sometimes, you may have troubles in updating by Envato Toolkit. So another way is to update
via FTP. However, this way will take more time because you have to do step by step manually.
Step 1. Login you Envato account. In Download tab,
find Hotel WP and choose the Installable WordPress Theme
(the WordPress file).
Step 2. Login your server, then go to wp-content/ themes
folder and backup your hotel-wp theme folder if you
want or delete it. The content in your site will not be lost but if you have modified code, the changes
will be lost. You have to reapply them after updating over.
Step 3. Exact new file hotel-wp.zip
you have already downloaded from Themeforest.
Step 4. Drag & drop new theme folder hotel-wp to wp-content/
theme to override the existing files.
