i stayed at the cosmo last time i was there, with balcony fountain view. i was rather disappointed in it tbh, the view was the only good thing, the room was not as nice as the wynn or venetian/palazzo. bellagio is next on my list to stay at. helicopter through the grand canyon would be fun. i rode horses through the mountains (red rock canyon), which was lovely and great views. i like hash house a go go for breakfast, grimaldi's for pizza (better than the secret pizza in the cosmo imo). nobu is good for a splurge. yardbird was good for southern comfort food.
Where is Grimaldi's?? DH is a pizza freak so we always love trying new pizza places.
