Just act like you belong there, and know where you are going, and you should not have any problems.  It's a big help if the provider lets you know ahead of time where the elevators are, saves you looking around.

When you get to room, do not knock like you are trying to beat down the door.

I bring a gift of candles from Wal Mart in a WM bag.  That helps make it look like I just went out and bought something I forgot.  Every little bit to disguise your true reason for being there helps.

Yup, every1 here pretty much covered it...

Hotel staffs are usually passive, they work in the hospitality industry, and customer service is their number one priority. They should never stop any one from entering the hotel. If they do, get the hell out of there, its a LE. The staff are passive, and will not stop any1 for any reason. Anyways, I never had any1 stop me from going in and doing the deed. I even ask several staff members the direction of the bathroom, bar, elevator on several occasions, and some change for the snack machine. They are clueless as to why I am there. They have no idea, I could be visiting family, friends, business partners, or whoever. I have even been in 5 stars hotels late at night sitting in the lobby, and just walking around outside, talking on my cell phone, talked while I enter and leave, and never been stoped for anything. Heck, I even bought a grocery bag, sandwiches, drinks, or what have you to the hotel. Those staff are clueless as to who enter the hotel.

But don't draw too much attention to yourself though, I may be different because the way I physically look. Don't be too loud, and pretend like you know what your doing. Gently knock on the door. Most of the times, the staffs are busy looking at the computer screens or doing something else like helping someone check in. It ain't too complicated, just make sure you don't look nervous or sweating Anyways, enjoy man.
