We were in Vegas 2 years ago in late June. Circus Circus is at one far end of the Strip - you will need to Uber or Lyft to enjoy most other Casinos. Don't let anyone tell you different - it might be "a dry heat", or it might be "very low humidity", but 115' is still DAMMED HOT! The Vegas Strip is all macadam and concrete. No shade anywhere! It's too hot to walk very far at all! Just my experience.
Two young retirees restless to GO!
Life is too short to wait too long to do all we want to do!!
Go and enjoy!!
