Planning on writing a campaign where the party begins in a stasis of some sort.
Wookieepedia lists Stasis chamber/pod/tube, carbonite, and cryogenic stasis. The cryogenic stasis is lethal after only a few hours, and carbonite or pod seems like it might fail for the time span I'm planning (several hundred years).
Do the assembled minds of this forum have further suggestions?
Pick whichever one you like. It's Star Wars. If you want to use cryogenic, go cryogenic. If you want to go carbonite go carbonite. The story trumps everything else anyway. So pick a method and go with it. Or invent a new one. The overall point is, if it's a required point to start the game then assume it worked the way it needed to and move on from there.
Specimen Containers are in Enter the Unknown. They can place the occupant into stasis or just provide life support at the option of the operator. I don't really picture these things being used for extended periods of time, but thye should work for a few weeks or even months if needed.
I'm fond of the original Han Solo Adventures novels, which featured a secret corporate prison using stasis chambers (where they kept the original Outlaw Tech.)
But nothing is more Star Wars than Carbonite.
The Star Wars: The Old Republic MMORPG has the leaders of Taris placed in carbonite for about 300 years - the time between KOTOR and SWTOR. Though there could be fatalities (carbonite freezing is always dangerous), most were expected to survive.

This. Absolutely this.
Sure, there are dangers with Carbonite, but that doesn't mean your players can't survive. Or maybe there is some experimental cryogenics system that works. It's all about the story, so let your creativity run wild.

Wookieepedia is edited primarly by otaku with smelly feet that only consider certain sources worth mentioning and remove anything else.
WEG sources, (the first RPG line that also established much of the tech, craft, and gear that because EU standard and is being recanoned in things like Rebels now) had several different appearance of stasis systems and carbonite freezing that kept the occupant suspended for extremely long times.
Go with what you need, don't sweat wookieepedia, for everything there that is solid, there's a source disproving it elsewhere.
in the EU, there was a character form the time of the Republic's formation (about 25000 BBY) who was put into Force induced stasis up until the time of the Rebellion: Arden Lyn.
Thank you all for your insightful answers! I think I've come to a decision.

I always felt like they were just testing it in Empire Strikes back, because nobody knew if it could house a living person. 
So I dunno if it would fit this adventure.
I know you've made your decision, but I still wanted to post the following for anyone else who might come along looking for similar input.
We've had a "stasis" case in our campaign that was none-of-the-above, and involved the Force. Have no idea if it was just created by our GM or what...
We acquired a Holocron that was the mind of a Jedi transferred to the holocron. Basically, it manipulated us into going to this ancient forgotten abandoned Jedi temple to release the body which the mind "belonged to", under the guise of leading us to some forgotten secret. The body had basically been entombed (for a couple hundred years, I believe) in a Force sensitive crystal that sustained/suspended the body, while the mind was trapped in the Holocron. Turned out of course the guy was a fallen-Jedi and he became our Nemesis, but that's another story...
That's an intriguing concept, emsquared

I think they're testing that particular chamber. Vader mentions it being "crude" so he needed to make sure it wouldn't harm a person.
If I need a stasis plot device, I would 100% go carbonite since it's iconic Star Wars. It's always fun to toss in those really recognizable things.
Or heck kill a few of them just to be a dbag or just make it work and Carey on.

The point is that, IF they would have carbonited a person before, there would be data about it. Experts there would know if it's lethal or not.

Yeah, but Anakin did it during the Clone Wars cartoon, so clearly he knows that conceptually the process works.
