NYC and Chicago at Christmas vs Yellowstone and Grand Teton

This holiday lights trip pairs two of America's most festive winter cities: three days in New York, then a short flight to Chicago for two more. In Manhattan, stand beneath the Rockefeller Center Christmas tree as skaters circle the rink below, browse the glass kiosks and free-admission ice rink of Bryant Park's Winter Village and walk Fifth Avenue's elaborate department store windows and light shows. Ride the subway to Brooklyn for Dyker Heights, where homeowners cover entire houses in lights, inflatable Santas and animated nutcrackers. In Chicago, sip hot spiced wine from a boot-shaped mug at the German-style Christkindlmarket in Daley Plaza, stroll the Magnificent Mile beneath trees strung with more than a million lights, skate at the McCormick Tribune Ice Rink in Millennium Park and end at Lincoln Park ZooLights, a glowing, family-friendly tradition. The best window is mid-November to early January: markets generally run from mid-November to Christmas Eve, the Rockefeller tree is lit in early December and most displays stay up into the new year. Visit before December 23 to catch everything open. Pack a warm coat, hat and gloves, because Chicago nights often dip into the 20s, and book hotels early.

Yellowstone and Grand Teton sit side by side in northwest Wyoming, linked by a short parkway, and together they make one of the great American road trips. Yellowstone, the world's first national park, holds more than half the planet's active geysers, including Old Faithful, plus the rainbow-colored Grand Prismatic Spring, the thundering Lower Falls of the Grand Canyon of the Yellowstone and terraced hot springs at Mammoth. It is also the best place in the Lower 48 to see big wildlife: bison herds in Hayden and Lamar valleys, elk, pronghorn, bears and, with patience and a spotting scope, wolves. Just south, Grand Teton's jagged peaks rise straight out of the valley floor above Jackson Lake and Jenny Lake, with sunsets that rival anything in the West. Fly into Jackson Hole or Bozeman, rent a car and plan on long but rewarding drives. Neither park uses timed entry, but in-park lodging books up months ahead, parking at Old Faithful and Grand Prismatic fills by late morning, and most of Yellowstone's roads close to cars from early November to late April, so summer and early fall are the main seasons.
