Location: Lakefront calm vs Strip centrality

The Westin Lake Las Vegas Resort & Spa – Location

The Westin sits on the shores of Lake Las Vegas in Henderson with a private beach and lakeside village nearby.

  • On 23 lakefront acres in the Lake Las Vegas community; Montelago Village is a short walk.
  • About a 20-minute drive to the Las Vegas Strip; Reflection Bay Golf Club is adjacent.
  • Good base for watersports, hiking and quieter evenings away from Strip traffic.

Choose the Westin for lake access, outdoor activities and a quieter setting away from the Strip.

ARIA Resort & Casino – Location

ARIA is in CityCenter on the Las Vegas Strip, steps from other major casinos, shows and nightlife.

  • Central Strip address near The Cosmopolitan, Bellagio fountains and major venues.
  • Walking access to restaurants, clubs, shops and performance venues like Dolby Live.
  • Airport is close; ground transport options are plentiful for Strip travel.

Pick ARIA for immediate access to the Strip’s dining, gambling and entertainment scene.

Rooms: suites and views

The Westin Lake Las Vegas Resort & Spa – Rooms

The Westin offers lake- and pool-view rooms and a range of suites and villas suited to families.

  • Total of 493 guestrooms and suites across multiple room and suite types.
  • Room types include Pool View, Lake View, Junior Suite, Luxury/Grand/Presidential Suites and Villas.
  • Many rooms emphasize lake or mountain views and larger footprints for families.

Better for guests who want family-sized rooms and lake or pool views.

ARIA Resort & Casino – Rooms

ARIA has a large inventory of contemporary rooms and suites with in-room tech and city views.

  • About 4,002 guestrooms and suites (wide variety of room types and sizes).
  • Rooms include modern amenities such as minibars, LCD TVs, separate tubs and showers in many units.
  • Designed for guests who prioritize modern design, tech features, and proximity to Strip attractions.

Better for travelers seeking a large variety of contemporary rooms near Strip entertainment.

Dining & drinks: lake-view dining vs a wide restaurant lineup

The Westin Lake Las Vegas Resort & Spa – Dining & drinks

The Westin focuses on lake-view and family-friendly dining with a few specialty outlets.

  • Marssa Restaurant (steakhouse & sushi) offers lake views and operates limited evenings.
  • Casual options include Rick’s Café, Pool Grille, Marrakesh Express and Arabesque Lounge.
  • Smaller on-site dining roster compared with big Strip resorts, useful for relaxed meals and families.

Good for relaxed, lake-view meals and family dining — fewer late-night or celebrity-chef options.

ARIA Resort & Casino – Dining & drinks

ARIA has an extensive and varied dining roster across many cuisines and late-night options.

  • Fourteen restaurants and 11 bars/lounges cover casual to fine dining and late-night drinking.
  • Known for high-profile and signature dining choices; room service available during limited hours.
  • Dining options make ARIA a destination for food-focused travelers and nightlife seekers.

Choose ARIA if you want many on-site dining choices and late-night options within walking distance.

Pools & beach (signature amenity): family waterslide and lake play vs multiple resort pools

The Westin Lake Las Vegas Resort & Spa – Pools & beach (signature amenity)

The Westin’s Nuala Pool complex and private beach underline its lake- and family-first appeal.

  • Two-level pool complex: upper adult-leaning pool with cabanas and lower family pool with waterslide.
  • Private beach access and seasonal poolside dining; lifeguards reported on duty.
  • Pool access and some lake activities may be included or available for a fee; cabanas and day passes available seasonally.

Best choice for families and anyone who wants direct lake access plus distinct adult and family pool areas.

ARIA Resort & Casino – Pools & beach (signature amenity)

ARIA provides multiple outdoor pools and hot tubs for a Strip-resort pool experience.

  • Three outdoor pools and three hot tubs with poolside bar and cabana options (reservations/fees may apply).
  • Pool hours and access rules apply; spa and pool services often require reservations.
  • No natural beach or lake — pools are the primary water amenity.

Pick ARIA for a classic Strip pool scene with multiple pools and cabana options rather than lake activities.

Wellness & nightlife: spa and quiet evenings vs large-scale nightlife and casino action

The Westin Lake Las Vegas Resort & Spa – Wellness & nightlife

The Westin pairs a full-service medspa and fitness studio with quieter evening options by the lake.

  • Ah Spa by Ageless Humans offers medspa services, body treatments and advanced therapies.
  • WestinWORKOUT fitness studio is complimentary for guests; sauna and steam room available.
  • Evening entertainment is lower-key — bars and occasional live music rather than nightclub-level activity.

Better for wellness-focused stays and quieter nights after a day on the lake.

ARIA Resort & Casino – Wellness & nightlife

ARIA mixes a full-service spa with a large casino floor, clubs, bars and late-night activity.

  • Full-service spa with bookings required for treatments; express check-in and concierge services available.
  • Large casino (150,000 sq ft), numerous bars/lounges, and nightlife options on-site and nearby.
  • Nighttime energy is high — expect crowds and late-night operating venues.

Best for guests who want spa time plus easy access to late-night dining, bars and casino gaming.
