I have a day pass to go to an Admiral's Club and I plan to use it this month (before it expires). I can use it either at the BOS or LAX airport. I've never been to an Admiral's Club Lounge before (usually, I like to walk around the terminals and check out the excitement)

, but for those who have been to both, which one is worth my while? (I dress rather casually when flying...so I hope that won't be a problem)
I don't really need the Admiral's Club for anything other than...well, I guess sitting around and perhaps using the (public?) computers. I don't know if I will be bringing my laptop on this trip, but there are wireless access, right? I probably won't be in the club for longer than an hour or two.
Any tips/suggestions on what to do/see to maximize my time in the Admiral Club's Lounge?
