Actually, the teleportation is not an issue, at all. Some relatives which are way older tried out VR at my place and they had no orientation issues with it. You get used to that really fast and don't feel disoriented. But personally, the teleportation removes some of the immersion, thus I prefer smooth movement.
Locomotion has one downside at first for newcomers. It can make you sick. That happens when 2 of your senses, one is your eyes and the other one is inside your ears receive different informations and push that info to your brain for validation, it will go into emergency mode for possible poisoning via stomach.
Thus, you should slowly go into locomotion and teach you brain, that this is a normal experience. Some people call it, to develop VR legs. Doing locomotion from time to time, you will not have any issues, at all. There will still be moments where even I feel sick after a lot of hours in VR. That's when the camera moves on it's own without you giving any input.
Well, I'll have to take your word on this.
