The Strip charges for almost everything. It doesn't charge for these. The Bellagio Conservatory and the Waterfall Atrium at The Palazzo are free, open around the clock, and rebuilt on a schedule most visitors never learn -- which is why the crowd standing in front of them is a booking decision rather than a matter of luck. Stay in the right building and you go down in your own time. Stay across the road and you cross six lanes and a pedestrian bridge to join a queue. Four properties put you inside that walk, and they are not interchangeable.
Bellagio: the Conservatory is downstairs from your room
Bellagio keeps the Conservatory just off the main lobby, which puts an elevator ride between your pillow and the display. A team of more than a hundred horticulturalists tears it down and rebuilds it five times a year, plants trucked in from growers in Utah and California, oversized props broken apart to fit through a back entrance from a warehouse off property. Go down late and the room is yours. No strollers, no tripods, no shoulder-to-shoulder shuffle past the centerpiece, just a full botanical build with nobody in it and Chihuly glass over the lobby on the way back. That is the entire argument for this hotel in December, and it's a good one.
Display: the Conservatory and Botanical Gardens, rebuilt five times a year. Where: off the main lobby, past the Chihuly ceiling. Access: free, open around the clock, no ticket. Best for: having the holiday build to yourself.

The Palazzo: a two-story waterfall under a glass sky
The Palazzo ends its run of the Grand Canal Shoppes in a skylit atrium built around a cascading two-story waterfall, with the planting around it changed out by season. Every room on the property is a suite, at least seven hundred square feet with a separate living area and a Roman soaking tub, so the walk from a proper sitting room to a garden under glass happens without a coat. That combination is rarer than it sounds on this street: most hotels make you choose between the space and the spectacle, and this one puts a door between them.
Display: the Waterfall Atrium and Gardens, replanted by season. Where: the Palazzo end of the Grand Canal Shoppes. Access: free, open around the clock, no ticket. Best for: a suite with the display at the end of the hall.

The Venetian: the atrium, plus the canal on the way to it
The Venetian Resort shares the same all-suite rule and the same indoor route to the Waterfall Atrium, and puts the Grand Canal and its gondoliers between your door and the display. That is more to walk through rather than less. The Shoppes run the full length of both properties and connect to the guest room corridors, so you can reach the atrium from your floor without stepping outside once, which matters more than it sounds when the desert turns cold after dark. Come in off Las Vegas Boulevard through the hallway past Carlo's Bakery and the canal arrives before the casino floor does.
Display: the Waterfall Atrium, reached along the Grand Canal. Where: the Venetian end of the Grand Canal Shoppes. Access: free, open around the clock, no ticket. Best for: suites, gondolas and a fully indoor walk.

Wynn Las Vegas: the garden the Boulevard never sees
Wynn Las Vegas keeps its two best things behind a manmade mountain, which is why the pavement outside gives away nothing. The atrium off the lobby runs on living trees and flowering shrubs with installations that shift through the year, and the Lake of Dreams plays music and projected imagery against a forty-foot waterfall from dusk onward, invisible from Las Vegas Boulevard entirely. The Aft Cocktail Deck terrace is the seat for it. Self-parking stays complimentary for hotel guests, which at this end of the Strip in December is worth more than the line item suggests.
Display: the lobby atrium and the Lake of Dreams. Where: off the main entrance, with the lake behind the mountain. Access: free to walk in, self-parking included with a room. Best for: a seasonal display the sidewalk crowd walks straight past.
ARIA: one room, two displays, no sidewalk
ARIA puts a free tram between you and the Bellagio Conservatory, which is the most useful thing any hotel on this list does in December. The tram links ARIA to Bellagio and Park MGM with a stop at Crystals next door, running on its own track rather than through the crowd, so the walk you skip is the slow one. ARIA does sit well back from Las Vegas Boulevard and the arrival walk is longer than most, and the fine art program strung through the public spaces is the reason that stops being a complaint. Museum-grade work, no ticket, easy to miss if you head straight for the elevators.
Display: the permanent fine art collection, plus a tram to Bellagio. Where: through the indoor and outdoor public spaces. Access: free, tram running most of the day and into the early hours. Best for: reaching the Conservatory without touching the Boulevard.
Which one to book
Want the Conservatory to yourself: Bellagio, and go down once the lobby thins. Want the display and a separate living room: The Palazzo, or The Venetian if you'd rather have the canal between you and it. Want the version nobody is queuing for: Wynn, and take the Aft terrace at dusk. Want two displays and no sidewalk: ARIA, and ride the tram. The holiday installations go up around the middle of November and come down in the first days of January, and every one of them is free once you are inside the building, so the only thing a room is really buying you is the hour you get to choose. Everything else running across the season sits on the Christmas in Las Vegas hub.
