We are doing exactly the same Paul.
I would go through ALL of the hotels that you are interested in and book the best price you can find, and keep checking back a couple of times a week. I know that sounds a bit extreme but I booked in at the Paris Hotel for four days and got it for $119 per night and a $10 discount for
AAA (we have CAA). That rate is now up to $154 for three of the 4 nights we have booked. We stayed there this summer and it is a wonderful hotel and very central. As for shows we are going to see the new Cirque du Soleil show. Have seen Mystere and "O" and they are superb. IF you are interested "O" is a great evening. You can book (I think it is 3 months in advance) and would do it as soon as available as tickets go fast.
We also did the day trip to the Black Canyon at the Hoover Dam. It is a great trip for a day which is wonderful for adults and kids alike. Website is

We are leaving for LA on Sunday August 14th, booked into Vegas for 4 nights and then going over to LA. We may cut the trip short to 3 nights but will play it by ear. We saw Elton John this summer while there and he was great. Either he or Celine Dion are playing at Caesars Palace.
Anyway good luck. Shop around though as the prices go up and down and you can always "rebook" if need be to take advantage of the better prices.
Cheers,
