Car rentals - Yes! You can rent from them if you didn't schedule a car before hand.Just look up Downtown Summerlin on your gps, and you will see all the shops and restaurants a block over A couple little shops on sight and a MASSIVE shopping mall/market within walking distance (literally across the street).8 full service restaurants (all amazing restaurants, with low to high price ranges), & a large food court with multiple choices, & a buffet (it was closed due to covid).POOL SIDE NOTE: During the 'off' season (Las Vegas winter), they shutdown the main pool with exception to 2 small side pools, and heat them up, to be used as hot tubs! she was just so kind and funny, you will love her too!) its amazing and when you go, ask for Maria.
When you look at the Red Rock Casino from the outside, it doesn't 'seem' big enough to house all these different amenities/options available to you.
