Agreed, given the amount of damage the Hosts seem to receive each day it doesn't feel plausible that they could collect them all and do what seems to be a manual operation on each to return them to perfect condition overnight.
My initial reasoning was that the park doesn't get continually reset every day, nor does it necessarily happen over night. It gets reset when a storyline finishes or a catastrophe happens in one location, e.g. the shootout in the starting town. It would make sense for guests to be given allocated windows for entry (note how the park is clearly not teeming with players, we meet perhaps 10 extras over the course of the entire series). Then that 'game' gets run, people play through the stories and then a new cohort begins. This might take, for example, a week.
We see the transition from the church in the Maze town being totally covered in sand, to being unearthed again. That clearly isn't an overnight (or even a week's) job.
Recall William had to get permission to launch an incendiary attack at the prison. It's possible that the control centre would deny the use of dynamite to a player if it was used in a location that would be frequently re-used.
Something else you pretty much just have to accept is that through all sorts of mayhem, the humans stay safe (well, until the end at least). There's some rather inconsistent hand waves around guns and bullets but one has to believe there are still ample opportunities for serious injury in some of the scenes we see.
Edit: popular holiday destinations like Mexico are reasonably dangerous, maybe Westworld is on the other side of the border ;)
Especially since a lot of hosts "work" at night. :)
Yes, the hosts are busy, but it's definitely possible they could be recalled to a location for pickup (or whatever) when they're free.
[SPOILERS]Dolores kills a human outright by aiming at their head mid-season. Then it isn't mentioned again.[/SPOILERS]
I always assumed something in the suit lining made the guns faux-fire, and the suit responded by exploding a pocket of air or something. But then you can see The Guy In The Black Suit (I've forgotten his name) load his revolver by manually inserting bullets, so I have no idea how that'd work. It's probably one of the only things that bothered me about the series.
It doesn't especially bother me though. We know that TV and movies generally have a convention that trauma that would put someone in the ICU in the real world is brushed off as a flesh wound. And I'll accept technobabble about the bullets. I'm also happy to accept that maybe Westworld takes place in a culture where theme park risks on par with base jumping are considered fine and proper.

Unless we achieve the ability to essentially run a MITM attack on the brain, to intercept commands from the brain and to provide it with sensory input, VR won't come close to being something genuinely deserving the name virtual reality.
There are scenarios where you are more constrained in real life (e.g. sitting in a vehicle of some sort) where g-forces aside, you can probably get pretty close with vision, sound, and some fairly basic force feedback will be able to get you to a fairly decent simulation. But I agree that anything involving running around and physically interacting with a 3D world is a lot more challenging.
Currently you can't even really walk around in a room without being incredibly restricted in terms of room layout, furniture and let's not forget you the headset with cables attached.
Last but not least even this hypothetical virtual reality is still just that: virtual. Simply the knowledge that something is merely virtual will always be somewhat of a disappointment, the same way a copy, no matter how perfect, is not quite as appealing as the original.
The concept of Westworld has an authenticity to it, that virtual reality can never hope to reach. As humans we are just weird that way.
