Thanks, thereuare, for the clarification on HW and PL rate methods; it's useful info for understanding the behind-the-scenes of quirky pricing differences we've experienced (I've been using frequently for 5 years). The zbenye multi-night observations are the same as my own, but one cannot conclude the rate-determination method used from only that empirical information (hence my own inaccurate assumption on averaging). However, it does further support the point (which may have been lost) I was making for new users, which is that multiple bookings may be needed, and not to rely on just one source of information (i.e., PL or HW) or one set of dates. Lindabobhat's reply was excellent advice. Hotwire is a great tool for lodging, but it shouldn't be an exclusive one, especially in Vegas. New users can save $$ with PL or HW, but some bargains are better than others, and over time can be significant. I hope most other users would concur with this. And, of course, this forum is an excellent resource for getting the best bargains....
