I'm taking my sister and 2 other girls (all mid to late 20s) to Vegas June 18-21. We leave on a red eye and will have 3 full days. We are staying at the Excalibur. I'm the only one who has been to Vegas before. I'd like to start using the Comp strategies this trip. Has anyone tried to do that while still sightseeing with first-timers? Any advice would be welcome.

I have already read The Frugal Gambler and am in the middle of Comp City in preparation.
