Unlike at the Metropolitan Museum of Art, where tickets are valid for three straight days, MoMA still sells only a one-day ticket. The museum ought to consider a multiday offer, especially if it’s encouraging visits to both the larger museum and PS1, too. Until then, if you plan to visit several times in the next year, it’s cost-effective to buy an $85 individual membership. Members get in free and can visit for a half-hour before the general public each morning.

You should plan to visit more than once anyway. MoMA’s curators will be regularly rotating the collection displays; come April, all 20 of the westernmost galleries will be rehung.

I’m still in the lobby, and I’m confused. Which way do I start?

I’d suggest starting on the east side of the museum. (Look for the suspended helicopter.) Take the escalators or elevators to the fifth floor, where the chronological display of the collection (1880-1940) begins. You’ll see Cézanne and van Gogh with new company, and then discover “Lime Kiln Club Field Day” (1914), the first feature-length film (according to MoMA) with an African-American cast.

The galleries are numbered, so you can work counterclockwise, moving from the older building into the new wing and back. If you’re enjoying the chronological approach, you can do it again on the fourth floor (for postwar art, 1945-75 or so) and the second floor (for contemporary art, from the late 1970s to the present ).

But if you’re more adventurous, head west from the ticket desk, hit the design gallery and Projects gallery, then hop on the new “blade” staircase by Diller Scofidio + Renfro/Gensler. This way will plunge you into the middle of the timeline; ascend to the fifth floor for Amy Sillman’s exquisite Artist’s Choice show, “The Shape of Shape” (through April 20), and to the sixth for the new terrace.
