For now, you can’t / don’t have to put shortcode or anything into your page, I try to make it as easy as possible to use. You can see your rooms directly in https://your-wp-installation/rooms/your-room-name.
I have installed a demo site in here https://webs.sitebridge.net/hotel/
The output page is still in pure HTML so you can style it any way you want. I plan to have on/off feature to use jq lightbox or not in the next release.
and don’t forget to download the latest version (0.2.1r1) since the 0.2.1 have bug in room-types view..
Thx..
