Thank you so much for your kind reply. After coordinating with extended family, great news! We will be staying one additional day, bringing an additional family member, and staying on the strip. With all of that in mind, I am starting my research fresh.
Here are the parameters:
3 nights
Thursday 8/10 late check in (driving from LA in the evening)
Sunday 8/11 check out
Room 1: 1 adult - any room type/view is fine
Room 2: 2 adults and 1 10 year old. We would really like a strip view, and are hoping to book whatever deal we can get through Priceline or Hotwire, then tip for upgrades at the front desk. We have had great success with this approach at Delano, Treasure Island and a few others.
We will need two beds or 1 bed and a pull out. We will probably all check in as a group. If there is some kind of extra guest fee, I will pay it. I suppose it is more work to accommodate more than 2 people from a housekeeping and resource use perspective, so I can reconcile that. Both reservations will be on one credit card.
While we are there, we plan to visit the strip attractions like the High Roller, M&M World, Tigers at Mirage, Bellagio Fountains, Caesars Palace, Pirate Ship show etc etc etc...
Thank you again for your help. My first stop will be looking for current deals via your links. Then I will post in the appropriate forum if I have questions on the hotels offered.
