It’s that time again.

Soon, hundreds of thousands of tennis fans will converge at the Billie Jean King National Tennis Center in Flushing Meadows, Queens, for the United States Open Tennis Championship, Aug. 26 through Sept. 8.

The competition this year promises some high stakes action. Will the American teenager Cori ‘Coco’ Gauff, the feel-good story of Wimbledon, make it past the early rounds? Could Roger Federer, 38, snag his 21st grand slam title? Will Serena Williams, 37, finally tie Margaret Court’s slam record of 24?

The crowds at the U.S. Open, however, can be overwhelming for even the most tennis-obsessed. Luckily there are spots — granted, many of them overseen by corporate sponsors — inside and outside the grounds that can provide a bit of an oasis, should tennis burnout strike.

Let’s face it: Free ice cream sandwiches and plush chairs in an air-conditioned, activities-and-amenities zone probably means there is a corporate sponsor behind the effort.

If you’re a card carrier, it would be silly for you to overlook the American Express Fan Experience, a 20,000-square-foot space just inside the main entrance gate.

Visitors with Amex accounts can have their hair and makeup touched up or their shoes cleaned for free. And for members of the general public, who are welcome to walk through the main area for a blast of air conditioning, there are also interactive activities, like creating a mural with tennis rackets that splatter paint.

Heineken’s Red Star Patio Cafe, with its bright green stools and spacious tables just east of Arthur Ashe Stadium, is known among tournament regulars as a casual option for those who like to socialize.

Introverts might find the tennis chatter a bit much, but if you’re looking to debate the most recent Osaka/Keys tie break, or whether Tsitsipas could go all the way, this might be the place.

On certain days, the company will be giving out free tastings of Heineken 0.0, a zero-alcohol beer. Not a bad idea, after all, to pace oneself.

Regulars know that the Grey Goose Honey Deuce is the official cocktail of the U.S. Open. Last year, 228,000 of them were sold during the tournament.

But fewer visitors know that there is a suite inside Arthur Ashe Stadium dedicated to this drink. In addition to unlimited Deuces, the lounge offers other cocktails, too.

Is your head ringing after sitting behind a group of inebriated Sharapova fanboys from San Diego, or that guy from Toronto in the beer line who won’t shut up about Raonic’s serve?

Maybe it’s time to leave the humans behind and commune with some other creatures. A California sea lion, perhaps, or a Canadian lynx.

The tennis center is actually part of the 897-acre Flushing Meadows-Corona Park. It is the fourth largest in New York City. The zoo is about a 15-minute stroll (head southeast toward United Nations Avenue North) from the main gate.

The zoo’s aviary, enclosed in a Buckminster Fuller geodesic dome, is quite possibly the most charming (and definitely the chirpiest) oasis in the park.

Or maybe you just need to Zen out and play some golf. Flushing Meadows Golf Center has an 18-hole golf course with a waterfall (100 Flushing Meadows Corona Park Road).

The park also has places to fish, picnic, throw a ball around, or sprawl out on the grass.
