Party at Altitude Decor

The cocktail reception took place in an area inspired by urban parks and playgrounds, replete with lampposts and indoor greenery. Tables were decked with miniature Chihuly-inspired flower arrangements, tucked into beds of wheat grass. J&L Catering's appetizer menu included salmon in sesame-tuile cones, warm cheddar puffs with mango chutney, and miniature phyllo purses with brie and raspberry preserves.

Hopscotch outlines on the floor added to the playground vibe.

Designers used oversize cardboard boxes to form "graffiti walls" inspired by skate parks. Performers from the Actors Gymnasium entertained guest with circus-style acts.

Both silent (pictured) and live auctions contributed to the evening's overall take of $1.2 million. Auction packages include a four-night trip for two to Paris Fashion Week, passes to the 2017 or 2018 Masters Golf Tournament, and a yachting holiday around the Mediterranean.

After cocktails, the 600 guests headed to a dining room filled with a combination of illuminated rectangular tables, square tables without linens, and round tables with linens. Decor including suspended Slinkys, glowing orbs, and oversize paper daisies was intended to make guests feel "dwarfed," or child-size themselves. To underscore the evening's message, chair caps were decked with children's faces.

The evening's program featured a performance from singer Vanessa Williams. Her set included the songs "Colors of the Wind" and "Save the Best for Last." The backdrop featured an "Imagine" sign tucked into a collage of umbrellas and kites.

After dinner, guests hit the dance floor under the canopy of neon Slinkies as the Ken Arlen Evolution Orchestra played. After-party snacks from J&L included crispy chicken sliders, warm raspberry-brie croissants, assorted miniature sweets, crinkle-cut French fries, and miniature Chicago-style hot dogs served from a cart.
