Sounds similar to y recent MAN trip. Premier Inn is a great hotel so no worries there.
As for Glasgow Airport itself, I'm not familar with it at all

I didn't even know there were mounds! Where abouts are they? Also what dates are you going?
I'm not 100% sure about air scanner, but your camera should be ok in hand luggage. Don't forget about not taking any liquids as hand luggage. I think some airports only allow 100ml of fluid in hand luggage but other airport do not.
I believe Glasgow gets the PIA A310 on certain days so it will be cool if you catch that.
