I'll ignore all the P/R crap and just ask....11 days in Vegas?!?!?
The only way I could possibly fathom this is maybe if I were using it as a base for daytrips out to hiking, running, biking, etc destinations like Red Rocks....but even then I wouldn't choose Vegas.
What are you going to do for 11 days there, especially with so many things not open? Have you considered maybe 3-4 days in Vegas and then renting a car for a week and seeing other things in the Southwest? I mean, most people seem to get their Vegas fill in 48-72 hours...
