Use of hourly hotel T2, PEK when arriving from Europe

I will arrive from Europe into T3 and then travel to T2 for a domestic flight. Unfortunately I will be unable to check-in for the domestic flight until 5 hours after I have arrived in BJ. I am considering using an hourly hotel - which should I use? Can I access the T2 one with my luggage as I will not be checked onto my second flight? Thank you
