We stayed at the Palazio, well located, suites are very nice; check-in/out easy. Went to the Sphere saw U2 - Incredible; Highly Recommend (Get seats on Level 2 and above, or Level 1 Rows 1 to 20). Dined at BRERA osteria; Great food, great service, great price/value; close to the Sphere entrance. Gordon Ramsay Hell's Kitchen at Caesar's; Great service, good food, good price (Get the Prix menu), excellent drinks. Lunch at Cañonita; very good but pricey. Royal Britannia Gastropub; good food, good price, nice beer selection, good service. Suggest making reservations for dinner, especially on weekends.
I have not been to Las Vegas in 10 years, changed so much. There was so much to see and do walking around and in each of the resort courts/malls. Didn't do too much gambling. So, if you don't gamble, you'll have fun.
