Random thoughts. It's all expensive. We stayed at Luxor and NY NY. Walking? Once we went end of June. 120 out. HOT!!! The new strip all blacktop and buildings held in the heat. Buy water a lot, go in and out of hotels and casino's, take the bus or tram to get you out of the sun. You try to walk the whole strip in summer with that heat you will die, maybe.
Screw any tours, especially Grand Canyon. Rent a car at Tropicanna best deal outside of airport. Much cheaper than a tour and way more time to do what you want. The tours spend 4-5 hours picking up and dropping off people before leaving. Rip-off. Actually a car is cheaper than a one way cab ride old to new strip
Old strip, friends of mine swear by some hotels there that are re-furb'd. The street party on the old strip is the BEST. Great bands and wild people. I tipped a bartender $20 and he re-filled my souvenir 2' glass all night. I would go just for that LOL.
LV HD rents Harley Ultra Limiteds for $200/day. HD's best bike. Great ride in the desert, Valley of Fire
Lastly, when playing slot machines, cash out after every spin and get a printed receipt ticket. Use as many tickets as possible. My job in Buffalo is printing those ticket blanks. Ensure my future employment. LOL. We do virtually every casino in LV
