this is probably a bit too advanced for you if you're just starting out with quest and~or especially if you know nothing of coding, but if you're ready or you want to, you can take a look here:
viewtopic.php?f=18&t=5138 (HK's 'explore' and 'travel' code)
viewtopic.php?f=18&t=5137 (HK's Lists and Dictionaries guide)
-------------
as for jsut simply moving to another room, there's two scripts that do it:
MoveObject (moving_object, destination_object)
(you can find this in the GUI~Editor's scripts, I think it's under the 'object' script category, but am not sure)
or
moving_object.parent = destination_object
(this is done in the GUI~Editor through the 'set a variable or attribute' Script -> [expression] or whatever specific [option] it is)

you're going to have to understand basic code-if structure, nesting scripts, and etc, and for the more advanced "goto~warping" stuff, Lists and Dictionaries.
