Will it be faster than other inert gasses? No. It's abut the same since in all cases you cut off the O2, depending only on how effectively you replace the O2 with said gas.
Unlike nitrogen and nobel gases, CO2 is a chemical asphyxiant that can kill a human without limiting oxygen concentration in the breathed gas mixture. Inhaling CO2 at concentration of 30% is rapidly fatal regardless of how much O2 you add to it. 30% CO2 + 70% O2 is nearly as deadly as 30% CO2 + 70% N2 + 0% O2. The effects of carbon dioxide poisoning are well explained in the resources below
“In the last two decades of the twentieth century, hundreds of people have died of carbon dioxide asphyxiation near volcanoes in Cameroon and in Indonesia.” — Allison Stark Draper, in Coping With Natural Disasters Many worry about carbon dioxide in the atmosphere as a greenhouse gas. Carbon...

I don't know about any researches that would compare time to LOC from CO2 poisoning and from asphyxiation by simple asphyxiants (like N2 or Ar), but I could expect that CO2 may induce unconsciousness slightly faster, considering how aggressively it acts.
Yes, it's basic human biology and can be most easily observed in drowning people who, while well past the "consious/unconsious" point, still try to swim and even attack rescuers, all this while holding their breath.
Unconscious people fighting rescuers - that sounds like urban legends ))) I wouldn't take such stories seriously.
Same with placing your hand over unconscious person face. They will fight it.
That depends on the type of unconsciousness. If the person was put under general anesthesia, I doubt that they would do anything. Inert gas asphyxiation is able to induce the state equivalent to general anesthesia within 2 minutes, as proven by the experiments of F. Hewitt whose dental patients were fully anesthetized after inhaling a mixture of 95% nitrogen and 5% oxygen for 75 - 95 seconds (

Of course, if hypoxia sets deeply enough, there'll no oxygen to power the muscles so any fighting response will cease at this point.
People experience lack of responsiveness in muscles even before losing consciousness from breathing asphyxiants. I went through this stage too, as I tried N2O asphyxiation on myself, and I hardly imagine how you could "fight" beyond that point, after starting to feel yourself paralyzed.
What - i'm traveling to a destination with water. Never said that i'm gonna dive at the hotel's location, it's just a pit-stop
In the OP's country, citizens have registered residence address written in their passports. They are required (by law) to present passport before checking into a hotel. If you're a citizen who wants to pretend to be a traveler there, you'd have to move to a different city than the one specified in your passport. And transportation of a heavy cylinder across cities without having own car would be a pain in the ass.
Not having a car is common in the OP's country due to big expenses (many people don't have a good income there), lack of convenient parking places, and presence of developed public transport. If you have a car, it would be more safe to drive to a quiet place and carry out CTB inside the car than deal with hotels.
. I can say that I have 2 methods. The first is to fill a bag with nitrous oxide, put it on your head and seal your neck with duct tape. In principle, this is not difficult if you know how to do it correctly. The second method is to pump N2O into the bag, then attach the CPAP tube to the bag and mask and seal it so that oxygen does not get in. I tested the effect of nitrous oxide on myself, and I am 100% sure that it will work. Write what you think, it will be interesting to read. Any shortcomings, criticism, etc.
