preview pages inside a single page

1. You could create a category of posts called rooms and then build a rooms template that goes along with that.

2. You can create a custom post type called rooms and then build a rooms template that goes along with that.

These are the two main ways I would approach this, depending on the custom fields associated with the “rooms” type.

Thank you very much for your reply.
I don’t understand what do you mean by saying “build a rooms template”.
Should i made it all with Posts Instead of pages?
It will be good idea if i make for every room a page…
…and then in one page make with HTML divs for every one room that links to each page? :S

Thanks again.

consider to create a custom page template for the ‘room’ page;

in that template, call all other pages (or all child pages of ‘room’ if you want to organize the whole thing with sub pages) with a custom query, and display one main image (either a ‘featured image’ or the first image) plus an excerpt from each (child) page in an ordinary loop.

Thank you Michael.
Two last question.
why should i make a custom page and not just a simple page?
cause to make it looks exactly how i want,or is there is another reason???
And maybe if you know…wordpress support channel manager(booking-engines)???

why should i make a custom page and not just a simple page?

it is a bout the templates – the ‘simple page’ would be the general page.php (which I would keep in my theme in any case), but for your specific requirements, a custom page would be (imho) more useful.

cause to make it looks exactly how i want

that is one of the reasons; you can make the layout, and the selection of what you want to show, very specific.

Nice!
Thank you very much for the help!
