We are planning a trip to Vegas, probably in July. Excalibur or Stratosphere? We're on a budget, and will have a car. We want to see the kid-friendly stuff - and go see Lion King! We are considering: Adventurdome, Madame Tussauds, Secret Garden, Lion Habitat, Shark Reef, Freemont zip line, etc. Any suggestions and advice would be appreciated! Thanks!!!
