Over the course of the last 12-14 months I have had the occasion to stay at this JW Marriott location 4 times -- and each time the staff and amenities do not disappoint.
Even though I have checked in with different folks each time --- the front desk manages to remember (or read) my preferences and makes an effort to get the pref room location and type.
Room is very good size, big bed, great bedding, good lighting and plug access. The bed was hair/lint/dirt free and I didn't have any of the issues previously noted. The bathrooms are big - always immaculate and well stocked. Big wall mirror for dressing and good furniture for discussion areas.
Parking is super easy whether you use valet or self parking. I have used both. The parking guys always remember me and are going to get car before I ask.
There is a starbucks on site, several other restaurants and a real nice day spa with classes. Also a large mall area right across the street with a bunch of mainstream brand name restaurants and shops.
The back area is a large walkable garden and my favorite place to stroll after dinner. The trees shade the path and keep it cool during warmer months.
This location is great for me --- with business in the Summerlin and Red Rock areas. Easy freeway access to both the Summerlin Parkway or 95/15/215 interstates.
