Wife and I will be in Vegas During late December with 2 grandgirls (13 & 14 years old). I plan on taking a GC tour with the grandgirls. What I am looking for is a airplane flight from Vegas that will go over the Hoover Dam on the way to the South Rim. Once at the GC we would take a guided senic bus tour before deparing back on airplane. The tours I see do not go over/by the Hoover Dam on the way to the South Rim. Only if you go to West Rim do they go over Hoover Dam. If there is one that goes over the Hoover Dam please be as specific as and possible with one so I can check it out. Thanks for any help./info!
