Always get the guys to your floor and ask them to ring from there, I never give room number out till I know there on my floor . After bad experiences where guys have pretended to be there. Have a look at the decor and ask them a question they could only know if there. I used to give them room number if I could see them out side, but I had a few guys drop me in it and say where they were going!! This is for your security and decent guys always understand this, also you can be ready at the door to open, I tell them to open door like its there room and not to knock, but you will get the odd one who ignores these rules!! If you have a gym in the same direction as lifts these are the best, then if a guys a nervous type I explain this and say they could carry a bag on there shoulder, but this is rare.. Key holes are always best. I always book hotel for 2 people, I always have nappy sacks, you don't want any smells and I dispose of rubbish when I can,I tend to keep low profile in day of quiet hotels but that's me.i think that's it really as it all depends on hotel, but the most important is the make sure you don't give room number till your sure they are there .
