So I know how to transport the player using a trigger_teleport and info_teleport_destination, but it's very choppy and strange. I would like to know how to teleport the player so that they can see the area which they are going to teleport to, for example, how in PTI maps you are actually transported from the elevator-chamber hallway into the real map, but you can see into the map from the hallway with the monitor reading the test chamber number and title.

You're looking for the "linked_portal_door" entity

Or a prop_linked_portal_door, which looks like a normal door.

watch out with these entities named before; they can cause some graphical glitches when portals are in line of sight with them. So only use them if there's no other way!

also the prop_linked_portal_door is a gray door

It is? Isn't it what they use in the PTI?

pretty sure they use normal worldportals inside the doorframe.
Unfortunately currently my hammer refuses to start and my internet is so crappy that I can't verify game cache and download the fix so can't check right now

Yup, there's a linked_portal_door inside the door model. I don't think the prop_linked_portal_door is ever used in the actual game.

Thanks for the help everyone, world portals worked fine.
