One highlight of this trip had to be the Cheesecake Factory restaurant in The Palace Forums shop. They had great service and excellent food. For the money, it was a great place to eat. Next up would be the Fashion Show Mall, which has great shopping, and if you are not from this country, lots of stores you wouldn't normally see. Finally, I'd have to say the House of Blues in Mandalay Bay was a highlight. There were great food deals, excellent food, and good service.
Quick Tips:
If you like sea life, check out the Shark Reef at Mandalay Bay. Buy the ticket that includes lunch at the House of Blues restaurant in the hotel. It's only more per ticket for the lunch, and you get a full and very tasty meal!
Avoid the buffet at Excalibur; it's pretty sketchy. And unless you are really into "God Bless America," skip the Freemon Experience.
Best Way To Get Around:
Take the Monorail as much as you can if it's heading where you want. Just be aware that it's behind the casinos, so be prepared for the hike from the Strip all the way to the loading platform for the train. The LV Bus is also a good choice for getting up and down the Strip.
