See the art-deco plaza, Radio City area and (optionally) go up to Top of the Rock for classic Manhattan skyline views; Top of the Rock typically runs late morning through evening, but check hours and book ahead.
Enjoy a classic NYC lunch close to Central Park South; Sarabeth’s is reliable for salads, sandwiches and a relaxed sit-down. Many Midtown restaurants are open lunch hours (approx. 11:00–21:00), but check current hours and reserve if possible.
Take the E (or other recommended downtown service) from Midtown toward World Trade Center/Battery Park area — expect ~35–45 minutes travel including walking to/from stations.
Board Statue Cruises from Battery Park for either the full Liberty Island visit (with security screening) or take the ferry for close-up views from the water; island visits take longer, so book tickets in advance and verify seasonal ferry times.
Walk to the 9/11 Memorial to see the twin reflecting pools on the former Twin Towers footprints; the outdoor memorial is free and open into the evening (museum hours differ — museum usually closes earlier).
Choose a casual dinner at Eataly Downtown (Italian marketplace) or the eateries at Brookfield Place for quick, tasty options with views near the Hudson; most spots stay open into the evening, but check exact kitchen hours.
Take the E train from World Trade Center back uptown to 34th St–Penn Station (about 10–20 minutes) so you arrive with time to catch your 8:30pm bus. Trains can vary, so allow a little buffer.
