You can stay at our place George. We have a very comfortable futon! Warner Studios is literally one mile up the street from us and is a fabulous tour - well worth the money spent. I've done it a couple times when Ian worked for the WB network (once for free). They used to let family on the lot pre-911.
This is a real tour. You will see real shows taping. I'm not sure how many though, but it isn't hiatus time like May - August. They will stop the tramand offload you if there is something worth seeing, including approved outdoor shoots. As you go by the soundstages, keep eyes peeled. I saw Clooney when they were doing Ocean's 12 soundstage work.
They will also take you into the company museum. The old correspondence documents are a not miss.
The studio is literally over the hill from your hotel. It's just a big hill. Cab is easiest. Not sure which bus route will get you there without additional walking, as studio tour meets in a different location than it used to - not off a major street. Subway will take you directly to universal CityWalk. Just cross the street and take the shuttle up the hill.
Unfortunately ABD is during the last two weeks of our fiscal 1H year end at work and I'm a slave too it. 
I'll be with all of you in spirit though.
