i wonder why no one recommended the california academy of science in SF
if you are in SF, get their 9 day city pass. you get free rides on the trolley and muni. plus you get free admission to 4 places of interest including the SFMOMA and CAS
alcatraz is a must see but you may have to book way ahead of time. try booking on the internet
the grand canyon can be a one day event depending on whether you go to the west rim or south rim. the skywalk is in the west rim but the south is more interesting, but way farther.
places of interest in vegas, well just watch out for the daily street shows of the hotels (bellagio, treasure island, etc). mostly, its a walking tour of the gambling places.
try to see one cirque de soleil show. zumanity, if still running, is ... hehehehe
