I have stayed at Mandalay twice and also at Luxor. Many yeras ago I srayed at the Sands. The Sands no longer exists but I have a couple of souveniers.
As far as I am concerned most places on The Strip are OK to stay in. I would go for the best price.
CQ you actually gave the idea of trying a grasshopper. I enjoy them on a cruise.:-D Just thinking about it makes me want to book another cruise.
