Hi
If I remember the scenario correctly the hotel is in a relatively nice part of Seattle. As such, the locks are most likely a centrally controlled maglock system with passkeys keyed to specific doors - such keys would either be physical cardkeys or a code sent to your commlink.
Most missions assume a default device rating of 3 unless the description of the device says otherwise, so these would likely be rating 3 maglocks that can either be bypassed with the hardware skill or hacked by a decker.
For the hotel's host - it's pretty much impossible to convert SR4 nodes to SR5 hosts. I would just go with a rating 3-4 host with some non-lethal anti-intruder software.
Now for the cameras - assume that the cameras are connected to a centralized datastore/control system, and is most likely accessible through the matrix. You have three choices in how to deal with the cameras: disabling, spoofing, or messing with the data after the fact. Security specs with good hardware skills can do the first two, a decker can do all three.
Choices one and two are good for runners, three is not something a runner team should consider unless they find out about the cameras too late and/or did something criminal or stupid in view of a non-disabled/spoofed camera, and need to do some damage control after the fact. The main reason that method #3 is not a good one to rely on by default is that runners can't be certain that they got everything - something might have been copied off-site, perhaps by the security spider. Also, destroying files after the fact is a good way to get caught as the spider may be on the lookout for someone coming back to destroy evidence.
So you are really only left with two choices - disabling or spoofing. Disabling is easier - either hack the host or intercept the transmissions from the cameras to the central system and just turn things off. The big problem with that is that this will probably be noticed quickly - especially since there is a security spider at the hotel - but it might just get them enough wiggle room to do what they need to do.
Spoofing is a little harder, since then you're replacing the live video feed with something pre-recorded - you basically capture the same view that the camera has while no one is there, then you feed that view back to the camera making it think it's recording while it's just looping the same thing again and again. This requires some gadgets for the hardware approach or a stealthy decker for the host approach, but is much less likely to be noticed than say, turning the cameras off, or leaving them on and going back to delete stuff later.
In this mission I believe they need to get into a specific hotel room, so in that case they probably only really need to deal with one or two cameras on that specific floor.
Or they could just not bother as it's not a huge security risk to hack a rating 3 maglock and search someone's room, even if there is a camera in the hall. Unless the occupant of the room complains (which she won't do unless they mistreat her somehow once they find her), or they massively screw up with the maglock, the hotel has zero reason to be combing through video recordings for extra-suspicious people
They could even go the super low-tech approach of a baseball cap, a pair of shades and a jacket that can be turned inside out for a different look. No technical skills needed except to deal with the lock and near-zero possibility of getting caught if you keep your head down and don't look at the cameras.
