Bring a sleeping bag just in case you get one bed. Usually the hotels are pretty good at providing two beds. Call in advance and see if you can get that type of room requested on your reservation. PL doesn't guarantee the number of beds, but hotels are often kind enough to provide what you nicely request.

You should really check out betterbidding.com and biddingfortravel.com before you "play" with PL again. Those two websites provide tons of PL info.
