You’re never guaranteed good weather in London—rain is part of its charm—but the spring, at least, brings the blooms of the Royal Botanic Gardens in Kew and the Chelsea Flower Show (stunning enough to interest even those who don’t care about flowers), and a shift from winter coat to windbreaker. If you arrive in April, grab a pint and feel like a local while cheering on the runners in the London Marathon; or if you visit in March, head to the Thames for the Oxford vs Cambridge Boat Race, which is about as London as it gets.

New York wakes up in the spring after a long East Coast winter. Central Park thaws, the High Line blooms and the farmers’ markets sprinkled throughout the city roar back to life. Even veteran NYC visitors should be tempted afresh by spring exhibitions at the Guggenheim and the Met (such as Weaving Abstraction in Ancient and Modern Art), and this is the ideal time to catch a game. Pro move: the Yankees and Mets are the obvious choice, but you’ll have just as much fun (for less money) seeing the minor-league Brooklyn Cyclones.

This is the time when Parisian cafes set up their outdoor terraces, the local markets like Marché Bastille sell their freshest produce (or at least it feels that way), and the cherry blossoms in Parc du Champ de Mars bloom into life. You’d be hard-pressed to find a more idyllic time for a scenic cruise along the Seine. Bonus? In May, for the Nuit des Musées, museums across the city stay open late into the night and offer free entry.

All the usual reasons to visit Tokyo still hold true—the dizzying and dazzling neon-lined streets, the food (Tokyo holds the record for the most Michelin-starred restaurants in a city), the non-stop energy, the glorious feelings of disorientation. But springtime brings a literal cherry on top: cherry blossom season, when the city is adorned with pink and white blooms. You’ll find peak hanami (cherry blossom viewing) at Ueno Park, Shinjuku Gyoen and along the Sumida River.

Let’s be real: most of your time in Vegas will be spent indoors, and 80% of your time will be spent in casinos, nightclubs, shows or celebrity chef-led restaurants (from Gordon Ramsay to Wolfgang Puck). But! That 20% outdoors still matters. And it’s far more pleasant to stroll the Vegas Strip in March (highs in the 20s) than the summer, with highs routinely over 40 degrees. Even if you pay a bit more for a spring flight, you’ll have a more chilled trip—both literally and figuratively.
